I can't wait to meet Dr. Carrie Jones, ND, MPH in March at the BHRT Training Academy cruise! The speaker line-up is phenomenal!
There’s a very specific moment in perimenopause where your brain stops quietly absorbing things that feel overwhelming, irritating, or unfair. And instead of smiling through it, your nervous system sends an alert that says, “No. F*ck this.”
It can feel like a sudden mood swing, but there is actual physiology behind it. GABA is your calming inhibitory neurotransmitter in your brain. It naturally declines with age. Part of progesterone can also stimulate GABA. Unfortunately, progesterone becomes inconsistent during perimenopause. Without that steady calming support in the brain, your threshold for overload gets lower. The reaction isn’t irrational. It’s accurate. Your system is responding to the real amount of input you’re carrying, which I would bet is a lot.
What looks like “snapping” is often your body asking for clearer boundaries, slower pacing, or more support. When you treat it like a character flaw, you miss the message. When you understand the biology, you can respond without shame, guilt, or self-critique. And most importantly, you can reduce the overload so you don’t hit that breaking point as often.
If you’ve been experiencing the “four-second shift” and want to understand why your nervous system feels different right now, comment GUIDE and I’ll send you my guide to what’s actually happening and what helps.
