Is it possible to overcome shyness?

ever since the start of college, the very few of the friends i had all went out of state for school and I'm attending a university in state. The problem I have is that I don't like to talk to unfamiliar faces, avoid eye contact, and excuse myself from situations in which I may have to do some conversing. Pretty much no contact with people. It gets boring and kinda saddening not gonna lie, but i tend to keep myself happy. I just wanted to know overall if it's possible to overcome this, If not I guess i can live like this. ^.^
