I have no social interaction. i keep my ringer on my phone off. i get anxiety when someone calls i don't answer or call back. what disorder do i have?

Get involved: You are young, life is short., i suggest you get involved with some activity for your over-all betterment. Whether it is a church, ymca, a club, community college, anything to get you out of the house and give meaning to your life. You need the connections as you grow older happy new year.

Rather than: Guessing - why not have a psychiatric assessment so you can actually get a better understanding of what is going on with you.

Social Anxiety: Disorder. You could be helped with psychotherapy. You do not have to live your life in fear. Reach out and start living a fuller life.
