Its essential to know your past and how your psychological developement is getting affected by it? Your concern may or maybnot be genuine about the present but  a good psychologist should always pay focus on past as sometime excessive and repeated failure can implant the seed of insecuriry about the future and in such case mild triggering factor or even the said thing just in fun by others can cause you great anxiety and to overcome it you show such kind of reaction. Anyway in such case you should definitely consult a very good psychologist who can bring your confidence back and can understand your concern. But if you really fight with this problem the foremost thing required is developent of optimistic attitude whatsoever be the situation. A great confidence like you can  bring any situation on the track.
