Many of us can call ourselves hypocrites but when it comes to a place like this, hypocrisy is nothing to be ashamed of. I agree with allofme, some of us reply to threads hoping it will be of help to us and there's a saying somewhere which goes along the lines of "the best advice we can take is the advice we give others" and it's true.
Imagine the situation you are in now, but you're talking to someone else in your exact same situation. You'd most probably tell them to stick it out, hang in there, lean on people for support and to talk about their issues.. that's what you should do. Sometimes it's hard for us to follow our own advice (gee.. if we all followed our own advice I think many of us would be in a better position than we are right now) but there's a part of us inside which CAN do it, sometimes it just takes a lot to pull that part out to the surface.
Take care of yourself.
