I suffer from this but im very up and down,and when i'm down I feel that i'm at rock bottom, but that is all to do with pms but I can turn nasty with it (like any woman i suppose)
I went to the doc's about it and he did give me anti d's but I wanted to try handle it on my own, which at the moment i don't think I am.
Go to the doc's and have a chat to them
