Well having lost some friends to suicide, one thing is, that you may not think anyone cares or people will get over it soon or something, it's not true. Something like that hurts everyone, even people that you would never think of. People care a whole lot more than they let you know sometimes, I don't know why they don't show it but it's there. Try talking to a friend who cares what you talk about just talk, or try and just get out run around the block a few times or something like that. Dunno if this helps at all.
