I've been doing really well for a while. But now my depression is back. I've been really mean to people I love. And I can't help it. I feel very violent. I don't know why. I want to cut myself or punch a wall. And everything seems to set me off. I don't understand. I've been fine for all this time. I finally learned to deal with what happened to me in the past. I don't understand why this is happening now,
I don't think I can control myself. I really really need to SI.

Can anybody help me?
