What now?

So like I said before, I am starting to feel a little better, but I still can't help this feeling of Now what do I do? Ofcourse I am really concentrating on school (trying to), and I blew my first set of blocks out of the water (much to my surprise), but there is this strange new hole in my life and I am not sure how to fill it. The truth is I think I have been a serial monogamist for the last 6 years, and even now the thought of being single petrifies me. So my question is, what do you do when you don't have a boy to take care of?
