I'm sorry you are feeling bad right now. It is the worst feeling to sit around and beat yourself up (I do this, too.) Do you have a therapist or councelor that can work you in?
I don't know what the deal is with lack of replies. I know my posts go unresponded to sometimes but I don't take it personally, so I hope you don't either. I have not logged in to this site in a week or two.
I hope you find someone to talk to or something to distract you from your sad thoughts.
