Why Do I Feel Empty

By Sophora Editorial  ·  Evidence reviewed  ·  Published June 2026  ·  Last reviewed June 2026

You used to feel like yourself. And now you go through entire days feeling flat in a way that has no particular reason. Not sad about anything specific. Just grey.

And you ask yourself,”why do I feel empty?”

Heavy in a way that a good night’s sleep does not fix and a good day does not fully lift. You wonder if this is who you are now. You wonder if you have always been like this and just did not notice. You have not. This is not who you are.

This is what perimenopause does to brain chemistry in some women, and it has a name and an explanation.

Low mood and depression in perimenopause are among the most common and least talked about symptoms of this transition.

A large clinical study of women attending a menopause clinic found that deep, persistent low mood was more prevalent than hot flashes in that group. More women were struggling with persistent low mood than with night sweats. And yet it is the night sweats that get discussed.

This article explains what is causing the low mood, why it is specifically a perimenopause symptom and not simply depression, and what the evidence says about what actually helps.

Someone important to you needs this too.

What low mood in perimenopause actually looks like

Perimenopausal low mood does not always look like what most people picture when they think of depression. It often does not involve crying, or hopelessness, or a loss of interest in everything. It tends to be flatter and quieter than that.

A persistent grey quality to the days. A reduced capacity for pleasure that is easy to miss because you are still functioning. A heaviness that arrives without a cause and does not lift in proportion to good things happening.

It can also arrive as tearfulness that comes from nowhere. A sensitivity to things that did not used to affect you. A sense of disconnection from the people around you that you cannot explain and cannot close the gap on. A feeling that you are watching your own life from a slight remove.

These experiences are real and they are biological. The distinction between perimenopausal low mood and clinical depression matters for how it is treated, and it is addressed directly below.

Why perimenopause causes this

Your mood is regulated by brain chemicals. Those brain chemicals are influenced by hormones. When the hormones shift, the brain chemicals shift with them. That is the short version of what is happening.

The longer version is more specific. Estrogen does not just manage your reproductive cycle. It actively supports the production and regulation of serotonin, the brain chemical most associated with stable mood, a sense of wellbeing, and the feeling that things are manageable. W

hen estrogen fluctuates and eventually falls in perimenopause, serotonin activity falls with it. The world does not become objectively harder. Your brain’s capacity to process it without tipping into low mood becomes reduced.

Progesterone adds another layer. As it declines, levels of a substance called allopregnanolone drop too. Allopregnanolone activates the GABA system, your nervous system’s primary calming mechanism. Lower GABA activity means a nervous system that is more reactive, less resilient, and more prone to anxiety tipping into low mood.

Estrogen also supports dopamine, the chemical most linked to motivation, reward, and the capacity to feel anticipation or pleasure. When dopamine signalling weakens, the flat quality that many women describe, the going through the motions feeling, is partly what that looks like from the inside.

The window of vulnerability

Research has identified what is called a window of vulnerability for mood disturbances during the menopause transition. The risk of depression peaks during late perimenopause and early postmenopause, the periods of greatest hormonal instability and fluctuation.

Crucially, research suggests it is the instability of hormone levels, the lurching up and down before they settle, rather than simply low estrogen, that confers the greatest risk for mood disturbances.

This explains why some women feel worse in perimenopause than in menopause itself.

Once hormones stop fluctuating and settle at lower levels, the brain adapts and mood often stabilises. The turbulent transition period is the most vulnerable window.

Understanding this is important: the low mood is not a permanent state. It is a window, and windows close.

Women with a history of mood disorders linked to reproductive events, premenstrual dysphoric disorder, postpartum depression, or sensitivity to hormonal contraceptives, are at significantly higher risk of more severe mood symptoms in perimenopause.

Their nervous systems have a documented history of responding to hormonal shifts with mood changes. Perimenopause is the largest hormonal shift of their lives.

What the research shows

Women in perimenopause are 1.5 to 3 times more likely to experience a major depressive episode than women of the same age who are not in the transition. The five most prevalent symptoms in a large UK menopause clinic study were fatigue, memory problems, difficulty concentrating, irritability, and feeling tense or nervous.

Hot flashes and night sweats ranked 18th and 14th respectively. Mood and cognitive symptoms were the dominant clinical picture, not vasomotor ones, in that cohort.

Around one in three perimenopausal women in the UK are being prescribed antidepressants or anxiolytics for mood symptoms.

Current clinical guidelines now state there is no clear evidence of benefit for antidepressants when used to treat low mood in perimenopausal women who do not have a diagnosis of clinical depression, and that HRT should instead be considered as the first-line approach.

That is a significant clinical position shift and most women are not aware of it.

What you may have been told that is not accurate

Myth: This is just depression. You need antidepressants.
Perimenopausal low mood driven by hormonal changes is a distinct clinical picture from primary depression. For women without a prior diagnosis of clinical depression, antidepressants have limited evidence for the hormonally-driven low mood of perimenopause.

Current guidelines in the UK and increasingly elsewhere now recommend HRT as the first consideration. Many women who have been on antidepressants for years during perimenopause find that HRT addresses what the antidepressants were only partially managing.

Myth: You are just stressed. Sort out your life circumstances and you will feel better.
Life circumstances contribute. Managing them is always worth doing. But perimenopausal low mood has a neurochemical cause that sits underneath whatever is happening in your life.

A woman with no obvious stressors and good life circumstances can still experience significant perimenopausal low mood because the brain chemical changes are happening regardless of what is on the outside.

Myth: Feeling depressed means you are mentally ill.
Perimenopausal low mood is a neurological response to a hormonal shift. It is no more a mental illness than a hot flash is a cardiovascular event.

Both are symptoms of the same underlying transition. The fact that one affects brain chemistry rather than body temperature does not make it a psychiatric condition.

Myth: HRT will make mood worse.
The evidence points in the opposite direction. Transdermal estradiol in particular has shown consistent antidepressant effects in perimenopausal women, particularly in the window of vulnerability. Women who have been told HRT will worsen mood are, in most cases, working from outdated information or conflating different types of hormone therapy.

What actually helps

Address the hormonal cause

HRT, particularly transdermal estradiol, has the strongest evidence for perimenopausal low mood and depression. A large clinical study found 69 percent improvement in persistent low mood after three months of HRT.

For women in the perimenopause window of vulnerability, this is now the recommended first-line approach in current UK guidelines before antidepressants are considered. The conversation to have with a doctor is not “should I take antidepressants” but “is this hormonally driven and what does that mean for treatment.”

CBT adapted for menopause

Cognitive behavioural therapy adapted specifically for the menopause transition has good evidence for mood improvement.

It works on the thought patterns that low mood generates, the catastrophising, the hopelessness, the distorted self-assessment, and builds practical emotional regulation skills.

For women who cannot or do not want HRT, menopause-adapted CBT is one of the strongest alternatives available.

Exercise

Aerobic exercise increases serotonin, raises dopamine, reduces cortisol, and improves sleep. Each of those effects directly addresses the neurochemical picture behind perimenopausal low mood.

The effect is not as immediate as medication but it is real, consistent, and cumulative. Walking for thirty minutes five days a week produces measurable mood improvements within three to four weeks. That is not a small thing.

Sleep

Mood and sleep are tightly linked. Night sweats that fragment sleep worsen mood. Low mood makes sleep harder. The cycle feeds itself.

Treating the sleep disruption is often the fastest way to break it. When mood lifts with sleep improvement, it gives you evidence that some of what you are experiencing is sleep-driven rather than a fixed state.

Magnesium and lavender

Magnesium glycinate addresses the deficiency that estrogen decline creates, including its effect on GABA and cortisol, two systems directly relevant to mood.

Oral lavender oil at 80mg daily has clinical trial evidence comparable to low-dose antidepressants for mild to moderate anxiety and depression.

For perimenopausal women whose mood is driven primarily by anxiety and nervous tension rather than clinical depression, this combination works on the specific neurological picture of perimenopause.

“The grey feeling is not who you have become. It is what falling estrogen does to the brain chemicals that used to keep the colour in your days. That is a different thing entirely. And it can be addressed.”

When to see a doctor

Before you go, use Sophora to prepare. Talking to a doctor about mood can feel harder than raising physical symptoms. There is often a fear of being dismissed, or redirected to therapy without the hormonal picture being considered at all.

The Symptom Decoder helps you understand and articulate exactly what is happening. The Doctor Prep document inside your Sophora account gives you the specific language to use, the questions to ask, and the framing that makes the hormonal conversation happen rather than being bypassed.

Questions you are probably asking

Is this perimenopause or am I actually depressed?

Both can be true at the same time. Perimenopausal low mood is driven by neurochemical changes caused by hormonal shifts. Clinical depression is a diagnosis based on the severity, duration, and functional impact of symptoms.

They can co-exist, and the hormonal component can make an existing tendency toward depression significantly worse. The important distinction is in treatment: if the low mood is primarily hormonal, HRT may be the most effective intervention, and antidepressants alone may be insufficient. A doctor who understands this distinction is the right person to help you work it out.

Will this lift on its own eventually?

For most women, yes. The window of vulnerability corresponds to the years of greatest hormonal instability. Once hormones settle after menopause, mood often stabilises with them.

But that window can last several years and it does not have to be endured untreated. Effective interventions exist and make a significant difference to how you get through it.

My doctor suggested antidepressants. Should I ask about HRT instead?

Current guidelines in the UK and increasingly internationally now state that HRT should be considered before antidepressants for low mood in perimenopausal women without a clinical depression diagnosis. Yes, the conversation about HRT is worth having.

If your doctor is not familiar with the current position on this, asking for a referral to a menopause specialist is reasonable. You are not obliged to accept a treatment approach that does not address the likely cause of what you are experiencing.

I feel disconnected from my partner and family. Is that part of this?

Yes. The reduced capacity for emotional connection that many women describe in perimenopause is part of the same neurochemical picture.

Dopamine, the chemical most linked to reward, motivation, and the warmth of social connection, is affected by falling estrogen. The disconnection you feel is not a relationship problem in the first instance. It is a brain chemistry problem with a hormonal cause.

Treating the hormonal cause often restores the connection that seemed to have gone.

In summary

Someone important to you needs this too.

The grey is not permanent. It is not you. It is a window in a transition that ends. How you handle it ,is what is important.
