You are in a really unique situation - college is a great time to meet people! Every semester you are exposed to new potential friends and new potential girlfriends. So college will help you tackle some of your issues - where can you meet girls - class, the dorm, the library, parties, etc.
As for HOW you meet them - try sitting next to a girl, saying hi in the hall waiting for class, if you wait for them to come to you - honey you may be waiting a long long time.
As for what to talk about common ground is always a good place to start - - class, cafeteria food, dorm life, etc.
A date is anything you do together - coffee, dinner and movie, a picnic, a hike, studying together, etc.
I think the mistake a lot of us make is thinking the state-appointed shrink is our friend. - Jack Handy
