Why menopause makes you feel like a stranger in your own skin

The Lunah Theory · 12 October 2026 · 6 min read

One of the hardest parts of menopause isn't the hot flushes or the sleep — it's the feeling that you've become someone you don't recognise. Teary over nothing. Snapping at people you love. Foggy and forgetful. Short-tempered in a way that isn't you.

It's real, it's physical, and it has a name: the hormonal shifts of perimenopause are reshaping how your brain handles mood, memory and stress.

What's actually happening

Oestrogen doesn't just regulate your cycle — it plays a role in serotonin, the brain's mood stabiliser, and in how well your brain uses energy. As it fluctuates, so does your emotional baseline. Add sleep deprivation on top, and the result is a perfect storm.

This isn't weakness. It's biology. And it's temporary, even when it doesn't feel like it.

You haven't lost yourself. You're in a season where your body is asking for more gentleness than it ever has before.

What helps

  • Name it out loud: "This is the menopause, not me."
  • Protect your sleep like it's a prescription — because it basically is.
  • Tell the people closest to you what's happening, so they're not guessing.
  • If the lows feel too deep or last too long, talk to your GP. There's real help.
