I want to start my social life over...but HOW?please help!?

Short answer: I would suggest getting a job at some sort of place like Starbucks. You can meet a lot of people that way. Also you can meet those guys you see at school, but just go on dates with them. If you go to parties with them, watch what you drink (roofies) and don't drink too much and feel them out. If they try to get you in bed that night well then you know they're not right for you. But you could also meet a guy who is legit and just wanted to get to know you better. You shouldn't generalize the guys at an entire school ;). You can also talk to those girls and become friends with them...doesn't mean that when you go out with them downtown or to bars that you have to drink as much as them or hook up with random guys. You can still have fun with them. Just don't be the friend who tells everyone else what they're doing is wrong. People thrive on differences, as long as there's some sort of similarity. If you can find anything to relate to them with, it's pretty easy to become friends.
