Ok, well, I have severe mood swings. One minute, I'm very jumpy, excited, full of energy, and yelling. The next minute, I'm all sad and depressed. I feel like I don't matter, I feel so empty...I feel like dying....Also, I get very anxious or irritated with my body. Sometimes, VERY itchy. I also feel guilty for no reason.....so plzzz tell me....what's wrong with me???
