Shambhoo,

You just have intense anxiety about social situations and as ctal put it, you might have social phobia. If you dont think you can function properly in public and are avoiding public areas because of this, then it is important so see a pschologist. Mainly because this might hinder in other things like working efficiently in a job setting etc. You might also develop avoidant personality disorder. Do you also feel uncomfortable in front of people because you think you might embarass yourself in front of them? If so, then I think you definitely need to go see a psychologist.

Boosting your confidence would be a solution for sure but it is easy said than done. And if you have no control in how you behave, then you need professional intervention. All the best. Please go seek help.
