definatley look into a local mobile response or crisis intervention unit, they will see and access him while he's acting out at your home, and they will advocate for you once you get to the hospital. This also is a way to get services set up quickly that your State may provide for children with behavior disorders.
My kids have Crisis Management Organization Benefits, each of my difficult child's has an in home therapist here once a week for 1 & 1/2 hours (at no cost to me), each has a SW who over sees all outside specialists working with difficult child's. CMO paid for 1/2 of difficult child II's camp this summer and will be paying for art lessons for difficult child I (if i can get gim to go). We have a FSO worker who calls me, to see how I am doing. I go to Family Support Orginization meetings bi-weekly where there are other parents in the same boat. They have a special "youth club" for difficult child teens, they do community service projects and fun trips. difficult child I of course won't go, difficult child II is too young.
I knew nothing of all these resources when I started out. Some States are better then others, I am still jealous of those who have respite! Of course we should "techinally" have a BA here 6 hours a week, but this is one area of the services that's been a bit weak, all the others are AWESOME!
