what do i do...he's 17.

And today he told me that he wants to die.

He has told me before. But i can't be with him right now. And it scares me so much, and it hurts. But every second he seems to be plunging further into darkness.

He doesn't believe that i love him.
And it hurts.

How do you calm down a schizophrenic when they are talking like that?

Loveshim, sorry we didn't get to this earlier. He needs more than what you can do for him, he needs help. Could you talk to someone in his family and maybe see if you can get him to get some help together? This is too much for you to carry on your own.
How are you two?

Try a high dosage of valium. No this is not a joke, I have been around psychiatrists and psych patients for most of my life now and I know it inside and out. Good luck finding a doctor to prescribe it. But yeah I think that would be a very effective treatment.
