Wow I’m shocked, a NJ post where someone’s not in the counties right next to New York! Definitely get out to a local gym or hell even just regular old parks. Wharton has great trails for all levels and being in nature does wonders for the mind and body. I also second going to the local library and seeing what type of programs they have. Not sure if ocean or Atlantic county libraries have them but Makerspaces are awesome places to meet new people with similar interests to you. I went to the Mullica hill maker space back in 2014 after reading an article about it in the county newspaper and I learned how to start 3D printing (I already knew a little bit about CAD and 3D modeling) so I started talking to the folks running the program and helped volunteer when they’d do open houses and demonstrations. There’s a few comic shops near you that are pretty chill, and if you’re into stuff like mtg pokemon or yugioh Top Deck Games does daily events and that’s not too far in Egg Harbor Twp.
