Answer:
Dear Abid,
It sounds like you may be suffering from social phobia.   Social phobia is an ongoing irrational fear of situations that may involve people analyzing or judging you, such as at parties and other social events or at school.  People with social phobia become overwhelmingly anxious and self-conscious in everyday social situations. They have an intense, persistent, and chronic fear of being watched and judged by others, and of doing things that will embarrass them. Sometimes, they worry for days or weeks before an upcoming situation. For some people, the fear may become so severe that it interferes with work, school, and other ordinary activities.  Sometimes anti-anxiety or anti-depressant medications help. But what seems to help most is practice. What I mean by practice is, to look in the mirror before you have an encounter and tell yourself, "I'm in control of my mind and my body, everything will be ok and I will successfully present myself in class(or at a party or wherever you are going) today." Say it and believe it. Look at yourself and say it over and over. The key is not to avoid situations but to make yourself face them over and over.  The other part to practice is with friends and family you feel comfortable with. If it's a speech, practice the speech in front of your family at home. If it's a social situation, practice with the friends you feel most comfortable with in a place where you feel comfortable. You will overcome this and you will be successful! Good Luck.
