criticism?

It is normal for an individual to feel fear of what other people think about them or how others perceive them....it is part of humanity...to seek for the approval of others. Everyone goes through it in some way or another....different people have different degrees of such feelings. The only thing that will make it pathological is if it causes a problem or disrupts your normal day to day activities. Then you should seek help from a professional. As what have been mentioned.....you should try to be a little more secure and confident about yourself. Believe in what you can do and what you can offer to other people. If you don't start believing in yourself...noone will. Try not to focus on what others think....but concentrate on what you feel is right. Listen to your inner voice...your conscience.

I think what you are lacking is self-confidence. You need to find faith and be sure of yourself. Stand tall and proud. There is no need to be afraid of criticism. In fact, constructive criticism can help you improve. ;-)
