When Perimenopause Changes Who You Are (And How to Find Your Way Back)

There’s a conversation I keep having... with friends, with women in our community, with myself at 2am when I can’t sleep. It goes something like this:

"I don’t feel like me anymore."

"I've lost my sense of self."

Not in a dramatic, existential-crisis kind of way (although some days, honestly, it edges close). More like a quiet, creeping realisation that the things you used to enjoy don’t quite land the same. The way you react to things has shifted. Your patience is thinner. Your tolerance for small talk has evaporated. You look at your own life and think… when did everything get so beige?

If that resonates, I want you to know: you’re not broken. You’re not depressed (although if you think you might be, please talk to someone). You might just be in perimenopause.

We hear about the hot flushes, the irregular periods, the brain fog. And yes, all of those are real and frustrating. But the identity shift? That’s the one that really catches you off guard.

Oestrogen doesn’t just regulate your cycle, it plays a significant role in mood, motivation, and even how your brain processes reward and pleasure. When those levels start fluctuating, it can genuinely change how you experience the world. Things that used to excite you feel flat. Your creative spark dims. Your social battery drains faster.

Then its all the other hormones that have a part to play in your rollercoaster of emotions. 

Testosterone influences our motivation, confidence, and overall mood. Low levels can lead to irritability, low energy, and depressive symptoms, while optimal levels support emotional stability and assertiveness. 

Cortisol – Known as the stress hormone, is released by the adrenal glands. Short-term, it helps the body respond to stress but chronically high cortisol levels can be linked to anxiety, insomnia, irritability, and depression, while low levels can cause fatigue, brain fog, and poor stress tolerance. 

Oxytocin – Often called the “love hormone,” promotes social bonding, empathy, and positive emotional states. Low oxytocin levels can contribute to sadness, depression, and reduced social activity. 

There are a whole host of hormones and neurotransmitters that are thrown out of whack when we navigate perimenopause. 

And if you’re neurodivergent? The impact can be even more pronounced. ADHD and autism are closely linked to how we regulate emotions and process sensory input, and hormonal fluctuations can intensify both. 

So it’s not just "perimenopause is making me moody." It’s "perimenopause is fundamentally changing how my brain works, and nobody told me this would happen."

It’s not always obvious. It can creep up slowly. Things you might notice:

🟣 Scrolling through your own photos and not recognising the woman who used to go to those places, wear those clothes, have that energy. Feeling a shell of your former self.

🟣 Saying yes to plans and then dreading them from the moment you agree.

🟣 Feeling disconnected from your partner, your friends, even your kids — not because you love them less, but because you’re struggling to feel anything with the same intensity.

🟣 Losing interest in hobbies you’ve had for decades.

🟣 Looking at your career and wondering what the point of it all is.

🟣 Crying in the car for no reason. Or no crying at all, when you feel like you probably should be.

🟣 Wanting to escape away from it all. 

 

Sound familiar?

For those of us with ADHD, autism, or both (hello, fellow AuDHDers), identity has often been complicated to begin with. Many of us spent decades masking, learning to perform a version of ourselves that the world found acceptable. We built identities around being capable, reliable, the one who holds everything together.

Then perimenopause arrives and the mask starts slipping. Not because you’re failing, but because your brain no longer has the same resources to maintain it. The executive function that kept you juggling everything takes a hit. The sensory tolerance that let you push through overstimulating environments shrinks. The emotional regulation that kept you "together" becomes unpredictable.

It’s not that you’re losing yourself. It might be that you’re meeting yourself (the unmasked version) for the first time. And that can be terrifying and liberating in equal measure.

I’m not going to give you a 10-step programme. If your brain is anything like mine, that’s just going to become another thing on the to-do list that makes you feel guilty when you don’t do it.

Instead, here are some gentle starting points:

💜 Track what’s actually happening. If you’re not already tracking your cycle, start. Not just periods... mood, energy, sleep, sensory sensitivity. When you can see the patterns, the identity shifts feel less like "something’s wrong with me" and more like "oh, this is a day-18 thing." I created a detailed cycle tracker specifically for this reason, it’s designed to help you take that information to your GP or healthcare provider.

💜 Build micro rituals. I wrote about this in a previous blog post, the idea of creating tiny, sensory anchor points in your day that are just for you. Not productive. Not for anyone else. Just a moment where your nervous system gets to exhale. It could be a specific mug. A particular playlist. Standing in the garden for 60 seconds. Whatever signals "this is mine."

💜 Let go of who you were. This is the hard one. The pre-perimenopause version of you was brilliant. But she was also operating in a different hormonal landscape. The you who’s emerging now might have different boundaries, different interests, different energy levels, and that’s not a downgrade. It’s an evolution to a new version of you once where you can find self acceptance. 

💜 Talk about it. With someone. Anyone. A friend, a partner, a community of women who get it. The worst thing about identity loss is the loneliness of it, feeling like you’re the only one who’s secretly falling apart while everyone else seems to have it together. Spoiler: they don’t. And the conversations that happen when you’re honest about that are some of the most powerful I’ve ever had.

💜 Declutter the noise. When your brain is already overwhelmed, the last thing it needs is more input. This might mean unfollowing accounts that make you feel inadequate. Simplifying your physical space. Saying no to things that drain you, even if you used to say yes. I put together the Gentle Organisational Bundle for exactly this. Practical, gentle tools to help you cut through the mental clutter when everything feels like too much.

I know it doesn’t always feel that way. Some days it feels like you’re genuinely disappearing. But what I’m learning (slowly, imperfectly, with a lot of trial and error) is that perimenopause doesn’t take you away from yourself. It strips back the layers that were never really you in the first place.

What’s underneath might be quieter. Fiercer. More boundaries. Less willing to perform. And honestly? I think that’s the version of us the world needs.

Go gently with yourself.
