sometimes you just have to worry about your school work first. once you are confident in what you are doing with your life, you will get more confident with guys. its easy to fall behind and get nervous when talking to guys, especially if you know you are interested in them. but they will never know how you feel unless you say something. i don't know what college you go to, but i am sure that if someone turns down your offer to get to know them, you'll have PLENTY of back-up plans ;-)
