A crisis intervention team is something I never had in place for my difficult child - because truthfully at the time, I did not know it existed. Had I had that in place for difficult child, his entire life, and mine, would have been drastically different. Instead, when difficult child got out of control, I was left feeling helpless and without any place to go or any way to get him help. It fueled my own rage, because I felt trapped and a victim of difficult child's rages. I also began to get out of control, like what is happening with you. At certain times, when he became entirely out of control, I would manage to get him to a hospital, which was always hard, but always helpful. Finally when difficult child was 6'3 and punched me in the back - it was over. I called the police, they took him and I found him placement - but that was after 17 years of me trying to help a mentally ill kid all by myself. It was not at all what was best for him or me. So, please get some resources and backup for him as well as you. The crisis intervention team is a great idea. Calling the police if he is violent and having them escort him to a phosph is also another option. He needs something in place that will cause him to stop and realize that what he is doing is horribly wrong, and that if he continues it will result in a life altering consequence. You are only a small part of this solution - he also needs procedures in place to stop this cycle.
