@nat9319 Plz don't try to deal with ur friend on ur own. You've got far to much to deal with yourself. Just plz try get him some help He's obviously crying out for it. But you can't possibly take it on alone. God forbid if he tries again and succeeds you'd have to live with the guilt forever and that wouldn't be fair. So be his friend but also get help from the "Pro's!"
Good luck sweetie. I really hope he'll be ok xx
