Not sure quite whether I'm peri or now menopausal (just turned 50), but I had been peri for a few years before I started HRT.
My main problem was being hot, all the time. Plus the usual stuff - brain fog, wondering what the point of my life has been, dwelling on all the mistakes I've made, anxiety about nothing at all, etc, etc, etc.
HRT has helped with some of this, though the main thing it did was stop my wretched periods which had become one long non-stop, half-hearted period.
As PP have said, I have no nurturing hormones now. I have always been very even tempered and a people pleaser, but now have to make the effort to be these things (before, it came naturally). The main change in me is that I absolutely cannot be doing with any drama. 17 yr old DD is a drama queen, and it drives me mad. My lack of interest in drama also drives her mad, so it's not a good dynamic.
Overall, I feel more the way I imagine men feel.
@Turquoisesea The Pill did terrible things to me, and I was very scared of HRT for that reason, but it has been completely unproblematic. I'm on Femoston.
