My facial tics prevent me from socializing

I blink a lot when I enter public spaces, especially at work and school, when I feel people look at me. And when an opportunity of conversation is coming, I can’t even look people in the eyes, because they get the contagious eye tic and it kills me inside. I literally run away physically at work when my tics are coming, ending the conversation short, because I’m ashamed. Now I don’t have friends. I don’t wanna go out with people. What should I do?
