So - the problem here really is your negative self-talk. You've already looked at it analytically and realized you have had wonderful girlfriends in the past and will again, and that you have the friends and skills you need to do okay in the single life. So the real problem is that negative voice in your head.

What you need to do is actually TYPE OUT some positive affirmations and put them in your pocket, attach them to your mirror, and repeat them several times a day. Just to over-ride that irrational primitive negative voice. You're halfway there, in that you recognize what's going on. Now do this step, however goofy it sounds.
