He's 13. I have 5 other sons. It's hard to support all of us financially because my wife passed away. My 13 year old son was the one who saw her die and it marked him. He suddenly became another person. He treats his brothers (i don't have daughters) very badly and insults them whenever. They get into a lot of fights. It's been going on for months but I just knew recently. I talked to him privately at night and he began fighting and cursing at me. He called me names. I never raised my son like that. All of my sons are polite and he was just firing bullets at me. I don't think it's puberty. He's been acting strange ever since he saw his mother pass away. But that was when he was 6. I give him more support than the others for only that reason. I comfort him more and all. He seems to be developing a wall against other people and he only wants to be alone. After he started cursing I chastised him and then he told me very very rude things so I slapped him. We got into a fight eventually and I stopped after he stopped. I think I hurt him too much. After thinking I went to apologize to him and I couldn't find him anywhere. I went to the bathroom and I saw him lying on the floor with blood everywhere and a knife near him. The great thing is is that he is alright. But after taking him to the hospitable the doctors showed me other cuts in his body. I never knew he cut himself. This is very hard especially when I'm not around very much. What should I do or say?
