Socially anxious: You have some anxiety is social situations, it sounds like. Try to look up some self-help materials online and see if you can do some behavioral therapy to get you through this. A psychologist well versed in these situations can help greatly. The role for medication is limited, but may exist if the above don't help.

Diet changes: Sometime if you eliminate spicy food, alcohol and acid foods (tomatoes) from your diet, you can decrease the severity.
