I got this from another thread and I think it will apply here somewhat.
Pinzelhead said:(1) You don't need acceptance from others. Overcome this need for acceptance and your fear of rejection should dissipate.
(2) Be humble. Lower your pride. The lower your pride is the less fear of being humiliated there will be and the less humiliated you will feel. Criticisms, rejections, and negative evaluations from others hurt less this way.
(3) Honesty and openess with others is the best way to go. Hiding from others always breeds fear and anxiety. Be confident with yourself and not ashamed.
(4) Learn to forgive and love other people the way you love yourself. Put other people's needs ahead of yours. Become selfless.
