But I went to several psychologists; tried various anti-depresssnts and mood stabilizers but none of them do anything for me.

You mention your friends moving away, this could be loneliness/isolation. Made me think of this article: Why Americans Suddenly Stopped Hanging Out

If I were to play "internet therapist" here (which is totally always a great idea) I would suggest to try spontaneity. Shake things up, go outside your not-so-comfort-zone, because it sounds to me like what you've been doing isn't working. And logic dictates the only way to find something that does work is by trying something different.
