jesus dude, I don't even know what to say to that. What is it you're looking for by posting that here? Do you want us to give you sympathy, or advice? Did you just feel you needed to get it off your chest? Do you want to talk to someone? I can give you all of these things.
I'm sorry things are so bad in your life that you feel it has come to something as drastic as this. I thought things were looking up for you? From your last few posts it seems your job was going really well and you were happy with things? That sort of up and down mood swing is a clear sign of manic depression, so my advice would be get to your doctor asap. Tell him exactly how you're feeling, what you've been going through, and ask him for help. He can prescribe drugs, or point you in the direction of a professional you can talk to.
If you want to talk to someone more in depth about your problems/feelings please pm me, I have a lot of experience with these matters and am a very good listener.
But do not do nothing, you clearly need help.
