Need help with 12yr old

He never showed emotion after my sister died his behavior is disrubtive he wetts the bed he has problems in school and now becoming very physical when he gets mad never takes ownership for his behavior constintly lies. He will do something right in front of you and will say that he didn't do it shows no emmotion towards anything until he gets frustrated then he becomes extremly angry and violent. He starts arguements and says threating and mean things to my son because he knows I won't let my son touch him my son is very angry about me keepig him here.He was hospilized and found to have PTSS and depression he is now on prozac but I don't think it is helping.Now he is being accused of sexually abuseing his 2.5 cousin.

I can't help you either but I do know your first priority is your own children.  I am sorry your sister passed away and I am sorry your nephew lost his mother (by the way, where is his father) but, as I said before, your first priority is your children.  Is it possible the social worker could find another place for this child to live?  Sometimes the better solution is the lesser or two evils.  Perhaps someone else on this board can offer more insight ...

I have heard that sometimes the Meds make them more aggressive could you ask if he can try some other kind for Depression, have you talked to the socalworker and asked these questions of her, You say he was abused well he needs lots of Positive attention now and interests, it must be hard on you with a Family aswell, you certainly need help for him.Has he a role Model in his life now some Granpa or guy they can do guys things with , does he like a sport, has he an interest you can encourage,he could also be saying mean things to your son because he really wants to be friends and feels left out.Can you talk to him one to one and ask him how he feels.
