Well, here I am, 17 years old. I dont know if I need help, but my mood changes many times a day. when I was about 11-14, it wasnt the case I had depression but was perscribed anti depressents and wasnt sad for about a year, but rather emotionless and happy. so I stopped them with conscent. But for the past year, I have had uncontrollable bouts of anger, sad for days then normal, but a situation last night, I was up untill 2am because I was really happy. I can be so happy, I make a fool out of myself. sometime, I feel happy and sad at the same time, which confuses me. Today, my little brother made me upset, and I bit, hit myself in the face, and cut my arm with scissors.... I go out of controll, I loose it, and I have no control over what I'm doing. My mood swings dont last more than a few days... and I'm mildly sad ushually during sad days with intenses saddness lasting only a few hours. But I'm TRUELY worried, that I may get an episode and put my little brother in the hospital or my mother. I'm affraid, if this happens, I may put myself in the hospital or a mental home. Is there something wrong here? Or is it normal teenage mood swings?
