Tonight, when I caught myself doing it, I tried to go back to the thought that I had before I started humming (actually, this time I started singing and moving to the music too, and it was much better because the music was actually playing!) Anyway, I think all these thoughts amount to are a serious fear of rejection. I was thinking about how I sounded talking on the phone with someone. And so I asked myself, ok, what was so bad about how I was? I tried to remain focused on that conversation, but I couldn't seem to get a grasp on exactly why it was so bothersome to me, other than that I feared rejection. I'm so glad you made that suggestion, though, because I can now start to work on this problem. Thanks
