How do you survive as an introvert in this society?

In my late 20s , really introverted. I have a lot of social anxiety as well so I try not to talk about myself for fear of being judged.

Our team at work had a bbq at a park today and it was torture. Everyone was talking about their personal life, dating life, etc and I had nothing to share. I also could not care less about what other people were saying. I feel that once again I do not fit in. I did not speak much.

I am just really tired of living in a society that is made for extroverted people. I feel I do not fit in anywhere.

How do you people do this?
