Sounds like a cry for help. If dude REALLY wanted to kill himself, he would have made it happen. For one, done it in a different and more effective way (OD, hanging, etc. etc.)..and for TWO, he would have done it when he knew nobody would walk in and find him before he died.
In any case, I have no sympathy for folks that kill themselves or TRY to kill themselves. There are many people that are dead that had no choice...and would have lived if they could. Life is a bitch, we all have demons and face difficult times...but life is a gift and suicide is an easy way out of a tough situation. Not to mention I believe it to be selfish as fuck.
I hope he gets help...he's funny as fuck.
