Are you sure you want to use such a permanent solution to something that could very well be temporary? You could meet someone tomorrow that will appreciate you the way you are. Maybe someone who has the same problems you do and need your help. I know it's tough now, but things can turn around in a heartbeat.
I hope you hang in there.
