Driving myself crazy!!!

Ok... so for about the last 8 months I have constantly been dating someone. Short-lived as each of the relationships may have been, I have always been with someone.
I got fed up a couple weeks ago. Fed up of not being interested in fantastic guys who liked me, and fed up with being interested in guys that didn't like me.
So I decided to take a break.
Here's the thing. I have become quite accustomed to having someone around. Having someone to call, someone to see. It has been ONE WEEK since the last one ended and I am going crazy. Thinking of all the guys that I let go of, wondering if I shouldn't have, wondering if I should have given them more of a chance, wondering if I should call them up and try again.
I know how I felt at the time when it ended, but was I just freaking out? Would it have gotten better? Was I stupid to let them go? Seriously, in my mind right now I am thinking of 3 different guys that I ended things with, that I'm now wondering if I should give it another chance, and those are just who come to mind right away, if I thought about it longer, I'm sure I could add at least 3 more to that list.
To add insult to injury I read this quote on someone's facebook page,

The mantle of spinsterhood was definitely on her shoulders now. She was twenty-five and looked it, and so there was no longer any need for her to try to be attractive.

Thank you Gone With The Wind.
