Ok, you need to find a hospital, any hospital today and quit stalling. When you found the almost fire, why didn't you call the police????????? The boy needs help, today. You are not doing him or your family any favors by waiting until his next appt.
The kid is downright dangerous and very very sick. I can't suggest anything else, my suspicions were that Abilify wasn't the right thing to give him. The doc told you 2 weeks to stabilze. It's been 6, didn't you tell him a few weeks back he isn't much better? I would say he is NO better, in fact worse. If you did tell the doc what did he say? Why is he resistant to Depakote? Many many children take it. It's not dangerous, I don't care what the doc says. The wrost side effect is weight gain, big deal compared to being an arsonist at his own house. So what if he knows how to control it, there are many things that can go wrong, and its the PRINICIPAL of the matter, no healthy child would do that. That is also one of the three signs of the profile of a serial killer, the other two are abuse of animals and bedwetting. Even if he wasn't bipolar, it would be cause for alarm, pardon the pun. There are many hospitals that take children, they get sick too. Call the police, juvie, they will know of the closest one, and no matter how far you have to go, take him.
I'm sorry if I sound blunt, but you need to face reality, hon. This isn't working, and your doctor is an incompentent fool. Let me know your thoughts and please tell me later that you took my advice, for everybody;s sake.
