I can understand what you mean...it's hard to get out there when you feel less than completely comfortable in your own skin. I think the best way to overcome that is to open yourself up to meeting people in places you do feel comfortable (e.g., the bookstore in the section of books from your major, dog park if you love dogs, etc.). The more comfortable with yourself you are, the better you feel and the more attractive you become.
Also, just for the record, people are out there that are attracted to all sorts of body types. Personally, I've dated at my heaviest and my lightest weights; the only difference was what I wore (my comfort level). Many times it seems like the media only celebrates one look, but there is someone for you who will appreciate where you are now.
Have fun with it, good luck.
