This is one of the pitfalls of "adulting" that so many fall into - many aren't leading a lifestyle that lends itself to relationship or friendship building, let alone social interactions on a regular basis.

I think in these situations it's important to utilize resources and create connections with those who have similar interests online, joining groups, creating a social media network, and the like. It's, of course, NOT a replacement for "real life" connections, but it does serve to check a box for us until we can find a way to get out into the world more often.

Wishing you the best and hopefully you can carve out the time necessary to build just as much fulfillment in your personal life as your professional life, you are most certainly not alone in this venture.
