"However, I've also lost all that time, where I could've been having fun, going out with other singles, and just getting on with my life."
Being, I wouldn't look at it that way. It's also a time to become detached, evaluate the situation, and, basically, heal. Personally, I liked the quiet and although I was lonely at times, when I decided it was time to stop being lonely, I was ready to get out there.
I used the time to try to get healthy and feel good about myself again. I would suggest that it is helpful just to hang out with other singles, or other people, for a while before you jump into the scene.
