Yes, I know just what you mean and I wish I could give you better advice. I have been told numerous times after a break up not to go and attach myself to someone else but I never listened. I am terrified of being alone. It has gotten me, like throughbeingcool, to get myself in many situations where I was taken advantage of because I wanted people to care about me. They never did.
I think you are smart in realizing you should stay out of the water for a while. I would suggest getting a good support group together. Maybe some friends who can do things with you (not going out and looking for guys) and keep you distracted. Maybe also look into a hobby you've always thought about doing?
Best of luck
