How can i make friends in mid 30’s

Hello all, I need some help/tips/mind set. I struggle with making friends. I used to be very social and had a decent size circle. But now I find it hard to meet people and build a connection. I find it hard to want to be around people. I feel like Ive let life get in the way, and if im being honest I feel like I’ve built a little cocoon. I currently live in Manhattan, moved here three years ago. I really only know people at work. I feel like I connect well enough at work but nothing too deep. I dont see them out side of work.

As far as meeting people i dont know what people do for fun anymore. I just work now and hang with my family. Any advice would be welcomed.
