Just wanted to echo a lot of what everyone else is saying...you'll be fine! First, I think the transition from high school to college can make you more outgoing to begin with, especially if you don't go to college with a ton of people from high school. Second, when we had our recruitment and I'd be talking to a quieter girl, I'd always put myself in her place and figure that I'd be pretty quiet too (even though I'm not usually a quiet person). I think you can tell the difference between someone who is shy and someone who is being quiet because they're snobby...I'm sure that the groups will realize that you're a great person and everything will work out. Keep us posted on everything
