Hello, Ran.
Why not step out of your comfort zone and talk to random people? Not with any intentions...just strike up a conversation for the sake of talking. "I really like your shoes" is a good one...sometimes even if the shoes are crappy.
Talk to people in the grocery store. Anywhere. I do that sometimes when I don't feel like hiding. As long as I don't run into someone who wants to tell me a life story it's all good.
What are you interested in? There has to be some groups you can check out around campus or in the surrounding area.
