Yes I agree with sparks19 as well. I know a very good family. They have three children and their one son is very disturbed. They have done all they can for him, sent him to a special school, therapy, but he is either bi-poler or has Schizophrenia or both. He has been violent toward his parents, chasing after his dad with a shovel and once hurting his mom vary bad.
Not that he is an adult they are truly afraid of him.
He tries to break into their house the police are there often.
Mom and dad are highly educated people so they were able to afford the best care possible for him and he did recieve it.
Their two other children live in fear of him as well. Both are doing well and are outstanding young people, oldest daughter is studing medicine.
So these poor people are kind of stuck. Unless they pick up and move across the country and start over and then still he can find them easy enough with the internet.
He has made their life hell.
I have known them for over 15 years. I remember this little boy of 6 who has turned into a monster.
To be afraid of your own child, to live in terror of him, that he will come and kill you in a fit of anger. It is hard to imagine more pain being brought on by a child.
