Some days are just harder. First holidays, Anniversaries, BDay's etc. I found doing things that would distract me were the most helpful.

The gym is great, do you have a dog? Do you like them?
I do urban walking groups when I get the chance (through meet up). It isn't a dating thing so there is no pressure, you just sign up for the things you like to do.

Hang in there.
