Hi
I was only 42 when I started experiencing some bizarre symptoms out of the blue. Extreme agitation. A few panic attacks. Insomnia. A dread of being left alone. A fear of the dark (pretty embarrassing in a grown woman). Fell out of love with my DH literally overnight. Didn't want to even cuddle my DCs and wasn't interested in talking with them. Avoided looking at myself in the mirror if at all possible. Lost the ability to read a book or magazine.
I had no idea what was happening. I thought I was having a nervous breakdown. The only physical symptom I had was that my usually heavy periods suddenly became very light and closer together, every 24-25 days rather than every 28-29.
I waited months and months before seeing a doctor, just really scared that I would be told I had serious mental health issues all of a sudden.
When I finally saw a consultant he told me that all my bizarre symptoms were basically caused by my hormones fluctuating all over the place thanks to early ovarian failure (this means that my ovaries were still working but not nearly as efficiently or as smoothly as before). He didn't even bother testing my blood until after he'd diagnosed me. My blood tests came back 'normal' but he'd already predicted they probably would.
He also told me that oestrogen regulates our feelings of well being and contentment. I'd had no idea 
I started on HRT 2.5 months ago. It has been quite hit and miss with my symptoms coming and going all the time. But since Monday I have suddenly been feeling much, much better and like my old self again. Hopefully this means the HRT is finally kicking in 
I know there are risks but there are tiny. There was a far higher risk of me losing my job or killing myself or my poor DCs feeling unloved by their own Mum. Life really was horrible beyond words much of the time
