Well, it's not much of a choice, because once you take it you can't take it back. I wish my friend who made that choice had told us all he was thinking about it before he did it. If only because even if after we had a talk and went through his issues, I would have liked to say goodbye to make absolutely sure he knew how we all felt about him, and how much he was going to be, and now is, sorely missed.
There's lots of good reasons why you personally SHOULDN'T die right now. Please talk to someone, Feanor. There is no hole so deep that others cannot reach down to pull you out.
God bless.
