Welcome to PC thinktank.

I remember so clearly when I started college. (my I must have a great memory!

) and how lonely and scared I was. I too was shy and even reluctant to go to the cafeteria because I was embarrassed to eat by myself and too scared to ask to sit with others. What a dilemma. But I gave it some time and slowly met some people in my classes and ended up making some good friends.
Maybe you could see a councelor at the university? Maybe it would help you brainstorm some ideas on how to work on this issue. Please take care. PM me whenever you like.
