Do you have any hobbies or interests outside of work? Is there something that you have always wanted to try but found it hard to start? Perhaps checking up on meetup or something like that...
Along the same lines, city intramurals ("beer leagues") could be an option too. In most places you can sign up as a single and be placed on teams that need more people. It has the advantage of getting you out of the house, doing something physical which can also help, and you get to consistently meet people? It's also harder to slack off and quit since you're part of a team.
That is a good suggestion.
If you feel like you dont have interests/hobbies outside of work, try beginning something new, even if it's a painting class at a community center.
