I'm currently In my 3rd year of Uni, and this is my first year living in the dorms. So far, I haven't seen anyone throw up, or heard about any Sv's floating around. I have my own room, and I share a private bathroom with 4 other girls.
I was scared as well before I moved, but its the best thing I have ever done! I've made some really good friends, I even told the RA about the extent of my fear, which made me feel alot better.
I really think you should think about going. I've only gotten sick once this year ( a horrible cold) and that was when I was away for christmas vacation at home!
there are so many things you learn at Uni, and not all of them come from a textbook 
see if you can request a private room, most Uni's will let people do this with medical documentation, I didn't even need one to get my room.
Its the best thing I have ever done. living on my own ( even if it IS in a dorm), has taught me alot of things, and you learn to be a little more independant in a less extreme environment, where almost everything is taken care of for you.
Its a good starting point, because one day you WILL want to live by yourself, and this is kind of like a baby step into it!
one thing I wanted to add is that cleaning/ hand washingis not a cumpulsion of mine,( I'mmore of a checker)and I still really havent gotten any sicker this year than normal.Edited by: Babydoll
