It does sound like social anxiety- We do need a little more information to confirm the diagnosis. Before that you should also look at ruling out any thyroid dysfunction etc. Once any physical cause of symptoms is ruled out the best way forward would be a combination of medication and therapy. Please visit a psychiatrist and a therapist . Exercise and meditation will also help with the anxiety symptoms.

Hello dear The above mentioned symptoms are indicative of social anxiety. Try consulting a clinical psychologist for proper diagnosis and treatment. Try to interact with closed ones in social gathering so to feel relaxed. Try deep breathing exercises and meditation to calm your mind. Discuss it with your parents.
