Yes honorsmum - sounds hormonal to me - it just happens despite circumstances and feels as though it's out of your control.
You're all really brilliant the way you are learning to understand and recognise that your feelings are hormonal, to go with them and recognise that the feelings will pass and you will feel better once your levels stabilise again (or your oestrogen rises!).
I went with mine but only because I was totally unaware I was peri-menopausal and knew very little about it!
Having said that - a few years ago several of us were discussing on here that once the hormonal fluctuations are over and hormones are stable, we never quite got back that wonderful zest for life that we experienced when we were in our fertile years. You have the lows, and the pms/pmt, but also the wonderful highs around ovulation and the enthusiasm for everything.
HRT will prevent you from being permanently on low mood (and some manage to be like this without it!) but I never experience those unrestrained highs any more. I'm not depressed but not hugely excited by life nor driven to achieve or experience in the way that I was. I do still get excited but at more extreme things if you see what I mean - whereas once it wouldn't take much! Nowadays I am moved by live music eg at festivals or gigs or when I'm in a beautiful place - scenery or architecture - and often in the sunshine, or perhaps by wild weather and seas.
I expect all this is related to libido too - but I won't go into that here  

As for girls - I am a woman and quite happy to be addressed along with others as "girls" - despite being 61. One thing - I never have been and never will be "A Lady" !!!!
Hope you're feeling more positive today honorsmum
