Thanks for asking. Your complaints are suggestive of social anxiety problem. If the fear of getting anxious is causing you to avoid exposing yourself to social occasions, it has impaired your social life , are you persistently anticipating about getting anxious in social situations, if it has  caused you immense personal distress, etc. These symptoms are highly suggestive of a Social anxiety disorder. Depressed mood, decreased sleep, reduced interest in routine activities,  irritability, etc could be other associated complaints. The positive thing is that it can be completely cured. A detailed Psychiatric work up, suitable therapy and few medications, if required can help solving the problem entirely.
