I have known many people who have attempted it at one point or another...I have attempted it...a cousin of mine attempted it a few weeks ago....luckily neither one of us succeeded...and I can tell you I did not intentionally leave any clues to anybody...i did not go up to anybody and tell them i was going to pick up a knife and cut myself or throw a rope around my throat, one i tried the other I clearly imagined doing. My cousin didn't tell anybody she was going to pop a bunch of pills...she just did. Besides, what could you or anybody else have done? Go up to the b oy and ask if he was going to kill himself? He would have just told you no...and you would have felt foolish, then he would have gone on to do it anyways...Suicide is the last refuge of the hopeless and those feeling that desparate feel that no one cares and will miss them when they're gone...including the one reaching out to help. Now, I know you know there is nothing that could have changed the events....but I also know that doesn't help you with your guilt and sorrow...and nothing I or anyone else here can help soothe the pain...but we can reach out to you and try. Maybe you should try and do something for the poor parents left behind...something personal. they will appreciate it...and you will to...if not now in time.
