Just remember that a large portion of your college's population is in a similar boat as you. They may have moved away from their families or their families are several hours away. Like you, they are starting anew and don't have any connections or relationships where they are at.

Think of that and try to approach people who you think might be interesting. People sitting alone are also great to approach - a lot of times they want attention, but don't actively seek it out, so they love when it's willingly given to them. If you're really picky, be very observant and look for visible clues that someone may share similar interests as you. Look for T-shirts, bracelets, fashion style (that maybe seem shallow, but it can't be denied that people meeting a certain criteria often have a specific outward appearance), and things like that that might provide clues as to what the person is all about.

Don't feel dejected if any of these people shut you out. You can be sure they won't remember who you are, so don't think you're making a fool of yourself. Once you find someone or people you want to spend time with, you'll be glad you tried.
