If I'd be in your position (lacking social contacts outside of the work environment), I'd take the time to reflect my life and would try to determine what makes me happy.

For example: Do you miss interactions with others? Join local clubs that fit your hobbies and meet new people. This is how life works IMO.

Personally speaking, joining different local orchestras/bands in the city im currently living in (since ~1 year) helped me a lot. I decided to let my work be only work and search "purpose/fulfilling" in other aspects of life.
