Emma, I'm so sorry to hear your news, what a horrible shock for you. I started at 35 which was bad enough though I wasn't diagnosed till last year (now 40). I was quite upset when I first found out and was really shaky and tearful, but once I'd got my head round it and read up on it a bit, I did adjust to it. I don't think any woman feels ready for this though, especially when it happens so early.
Don't worry about taking HRT - it's really no different to BCP, just a question of finding the right one for you.
There is loads of support on this site - have a look round at what is available. Once you adjust to what is happening it will feel more manageable and less scary! Also, as others have suggested, the Daisy Network is good for women your age - I've been fortunate in that my best friend is also going through early meno, but if I didn't know anyone else my age, I'd definitely be looking at the network for support.
Hugs x Dorothy
