Well, I have experience with teenage children but, my son seems to be a special case of some sort. To give background, he is actually my stepson. He was raised by his abusive grandmother. She took advantage of his mother and father's breakup right after he was born and his severe medical issues at birth to go to court and get custody of him. She then effectively shut the parents out of his life and raised him believing that nobody in a HUGE family wanted him, except for her. She completely isolated him, allowing no friends, contact with other family members, etc.
We recently were able to hire an attorney to gain custody of him. He has stated he is MUCH happier with us, has a life and friends, gets to do neat things that other kids do,etc.
Now we come to the problems. He shows no remorse for doing things he's not supposed to, even if they hurt other people, he lies constantly about everything, steals from family and friends, treats his friends horribly to the point where he doesn't have many anymore, shows no respect for the "boys don't hit girls" rules, is completely inconsiderate to his mother and myself but, jumps to when his dad says anything, seems to show a lack of empathy or compassion unless it's the cats or dog.
Recently, his obsession has been with drawing pictures of women tied up, gaged, blindfolded, whipped, beaten, etc. On top of the other problems we have been experiencing, I have to honestly say I'm scared. Of him and for him. He's seeing a psychologist but, it's not making very much headway right now. Has anyone else experienced anything like that? If so, how did you get past it/get your child(ren) help?
