I have a friend who tells me at the end of every phone conversation that he's going to go swim in the lake or drive his car into the lake. He's been saying this for weeks, possibly months (haven't quite kept track). I usually respond by saying oh, don't say that, whatever, etc. The reason I don't take it seriously when he says it is because he is known in our group of friends to be a very negative person. I've known him for a couple of years but one of our mutual friends has known him for more than 10 years and says he's always been like this. He is 28. I had a talk with our group of friends recently so that we can finally think of a way to help him. He goes to a therapist but it doesn't seem to be helping. He's never been to a psychiatrist or been on meds, so maybe that's what he really needs. He is also in love with a girl who severed contact with him more than two years ago (they were never more than friends by the way). He's pretty obsessive about it and doesn't understand why she stopped talking to him. He says he still cares about her. So...I know this a pretty loaded question..but what do we do? If it helps, he also comes from a family that isn't familiar with mental health issues and didn't seek help for him when he was a child.
