Bad day

It's been a really rough day here. Jake was 5150'd today by his school. For any of you who don't know what that means.....basically, if someone is acting or saying things that are "crazy" (for lack of a better term) the police are called in to assess the situation and possibly take the person for psychiatric evaluation. Well, Jake had his typical rough morning but usually when I drop him off at school, he pulls it together and has a decent day. He always apologizes for the way he's treated me when he gets home. Well, not so today. Instead, I dropped him off, he continued on his tirade and told his counselor he wanted to kill himself! This is not out of the ordinary for him to say (sadly enough, we hear this almost DAILY from him) The police were called and he was taken into the hospital. Now he's being transferred for further evaluation. I feel like I am in the middle of a bad dream. I'm a walking zombie. Even as I type this, it feels very surreal. I am hoping and praying that someone, anyone! can give me some answers on how to help him. I am lost. I don't know what else to try anymore and I'm very worried for what his future holds. I'm just praying that they can find something simple, something that's been somehow overlooked that would explain it all. I just want something I can read up on and understand. Some way to be able to get through to my child. Please pray for us!
