Fear Of Disapproval
Frequently people worry about the possibility that others might fail to show them respect and approval. While details differ for each person, the underlying factor is fear of disapproval -- people might think you lack intelligence, or other virtues and abilities.
Realize that the pain you suffer from worrying about this is much greater than that of actual disapproval.
Try to accept the worst. Imagine that every person who sees you will have a low opinion of you. Emotionally accept this. Once you've accepted this, although you might not like it, you will no longer need to worry about lack of approval.
