I'm afraid he will hurt himself or others. He's very violent about everything. Doesn't understand when to stop being negative. So many people have been a positive influence in his life (except his dad which he says to be close with but that's another story) and have tried to help him but he refuses help and doesn't think he needs it. He is always blaming himself for others mistakes, or well everything. He blames me constantly because I feel (mostly know) his dad always would blame me for everything and is taking on the same thing. It always seems to be getting worst. He has had suicidal thoughts like saying he was going to kill himself or this weekend while swimming he said he was gonna keep going deeper in the water until he couldn't touch and eventually drown. He needs help and I don't know what to do!
