I Have Social Anxiety

I prefer to be by myself, I just don't like people. I have always been one to go off and do my own thing. I do like to watch people, from afar, but that is it. My work is often after me telling me I need to get out more and do fun things, 80% of extroverts will never understand 20% of introverts in the population. I do not need to be around people. I often wish I could disappear and be invisible then I can watch people and they will never acknowledge I am there.
