How do you make friends as an adult?

I’m rly lonely and starting to make gfs but it’s hard to find ppl I actually connect with. I have some issues I’m trying to work thru in therapy - lack of self worth, anxiety, burnout. And I just don’t have any recent cute pics to show who I am, taking a break from dating, have a steady hookup, and feeling low. It’s hard seeing so many girls go out and have fun together. How do you make authentic friendships?
