Oh now you are in a bit of a tough spot and you have to let yourself "grieve" a little bit.
That's a long time to be with someone but once you're able to let the pain out then the healing can begin.

1. Don't dread being single. I was in a relationship for over 3 years (17-20) and that encompassed my dating life up to that point. After a couple of weeks I LOVED being single!! It was so awesome to have freedom and to get to learn about myself. To GROW into ME!! I am a couple years out of the relationship now and I am so much better for it. I have been in a couple relationships here and there since but nothing too serious.
I now feel like because of the time I have had to myself when I do find the "right" guy I will be in a better place. I now have learned a lot about myself and set a stronger foundation and am more confident in who I am.

2. Take things slowly... if you don't know what you like to do, try everything! Do yoga one week, go hiking another... try it all and give yourself time to get back in the game. By going to the gym and frequently attending classes you'll make friends there.

3. Don't dwell on what you lost and time wasted. Instead be thankful for what you gained and realize you did not waste your time. In those 6 1/2 years you learned a lot about love and being in a relationship which you can apply elsewhere. There were other things that you both needed while you were together and you had those needs met. Now it's time to meet your own needs and to eventually allow another to meet your needs and you to meet theirs.

It's a tough road of recovery but you can do it!
Hope what I said helps in some way...
