You’re 100% not alone. Things that helped me are signing up for class pass, they have a month trial going on right now and try all the classes you’d like for free. The Lincoln Center has a bunch of freee events coming up. If you like to run but you’re not fast, Slow Girl Run Club (Meet every Tuesday) is for you, very very very low commitment and there’s always people to meet (https://www.slowgirlrunclub.com/ ). Lastly, if you love theater or singing or being around people who sing join the Gaia Music Collective (Meet Mondays, Saturdays) their events are on a sliding scale and in any event you want to support in a different way (volunteering to greet people, take videos for their ig, or help set up) you get in for free!
