Err... Did not refresh the page to see all these responses. Sorry for the double post, but I can't edit my other post right now. Message boards confuse me...

Yeah, I think it might be hormones, too. That was my first idea. At least, I hope. The thing is, I started puberty when I was 10 (breast growth & period) and, I have not mentioned this before, but I did go through phases of depression and then bliss since I was 11, each phase lasting from weeks to months. I can't remember if they were this intense or not, though, since it was so long ago.

I am doing very well, theodora, and I have a GP. Okay, well, a doctor. I never really go there... but I am due to see him soon, and I suppose I should maybe ask him about this.

Thanks for the advice everyone.
