I'm no expert on the subject, but after having four friends attempt suicide and one actually commit it, I am somewhat experienced.
I'm surprised SR's the first to mention that it might be a suicidal act. It seems to me that that's exactly what that was. People that attempt suicide usually don't want to die. They need some attention, so they'll do something that seems like a suicide attempt, but actually doesn't kill them. So he takes a bunch of pills, but a dosage that won't kill him, and gets online and tells someone about it. He gets rushed to the hospital, and then starts to get the attention that he needs. That's what I'm thinkin. The most common ways for teenagers to kill themselves are razors for girls, and ODing for guys. So what he did, and the method in which he did it, leads me to believe that it was, in fact, a suicidal gesture.
