College must be hard to avoid social interaction all together. I would probably recommend joining something first off. It doesn't have to be a large gathering of a group, a small study group for a first step till you get used to it. Talk to the person you sit next to, small talk won't hurt. Ask them if they know of any clubs or something.
Study, study, study is a good way to waste time and I'm sure more opportunities will come to mind.
Buy an instrument, a small pet, take up making art, sports, hobbies. There is lots of option.
