I apologize that this response is so late in coming. I hope that your issue has resolved by now, but just in case, I will provide some information that may be useful to you and to others who might read your post.
I believe you have accurately identified the area that fits your issues - a form of anxiety, although it may be a severe one. Your repeated staring behavior and social discomfort seem to be obsessive behaviors that are becoming more compulsive, and you haven't been able to interrupt the progression. It becomes a rather vicious cycle, as you have been experiencing. The actual diagnosis can be made only after a detailed psychological interview by a psychiatrist or psychologist. Treatment can be very effective, and would probably include antidepressants and anti-anxiety medications. It may include long term use of such medications, but that is worth it to most people since it helps them return to a more stable place in their lives.
I wish you the very best of luck and recovery.
