Lately, my mood just sank into an all-time low. I'm angry and I don't think I have a good reason to be. For the past few days, I've been trying to overdose on anything that could possibly kill me. I know that's not good and I think about it and the angrier I get at myself. I don't know why, I think it's cause I get feelings telling me that I'm doing the wrong thing but I ignore them and go on and do it anyway. Then my guilt just follows me around that I can't take it anymore. And when I sleep, I either go on for several (>10) hours or keep waking up at random intervals and losing sleep. Is that normal?
