No Talent in Consoling

Let me first say I know all too well how you feel.

Secondly, you probably aren't the best person for supporting your friend, given your feelings on his and your own situation. I commend you for trying, but as ElectricSheep said it probably won't (and probably isn't) help your friend much.

One thing I think I've found is that when people come to you like that, they usually want pity, attention, and even justification for their position. While that might help them feel better for that moment, it does little in the grand scheme of things. What would really help is honestly assessing the situation and learning how to deal with it. Criticism can be a good thing if it comes from the right place.

Finally, if you really feel that your friend is suicidal please get him some help. That might be difficult given the online status of your relationship, but if that's really the case it can be the best thing you can do for him at this point.

Jam it back in, in the dark.
