Hi Mojo61, I am very similar to you too. My periods stopped 31/2 years ago and I had hot flushes but 2 years ago I suddenly got hit with anxiety and brain fog, which seem to feed into each other, creating a bit of a vicious cycle. There are times when I'm fine and think it's all passed, but it then returns. Trying to figure out what causes it. I take HRT which has stopped the daytime flushes but hasn't stopped the night time ones which come at 2 hourly intervals. Those make me feel that my hormones are still doing something or other and are therefore responsible for how I feel, and that ultimately it is all hormonal, and hopefully will pass. I've read in various places about women experiencing menopausal symptoms for a decade or so, which seems to suggest that though estrogen levels fall as Hurdity says, there must still, for some women, be some kind of activity which affects us mentally as well as physically. Anyhow, sympathies from me. Hope it passes soon...
