If you have social anxiety, which is I want to be honest, very new to me, you need to ask yourself why? Why are you feeling that why? How it all started? You are the one who can only attest what is really happening to you. There are introverts but being introverts are comes with a decision that some people would love to be alone than being social. In your situation, it becomes worst because of the word "anxiety". I feel sad that there is a person that is feeling this way. You can only overcome if you already know the answer to the question I mentioned above and how it is all started. There are people that do not bother to the words that you will be saying, why feel awkward? There are people that are too shy to be in the crowd, in front of the crowd, and this is one of the their greatest fear. What kind of worries you feel when you are with many people? If you can try to list it down, for sure you will realize something.
