Thanks everyone for responding with such thoughtful replies. Hugs to anyone else struggling to make friendships as an adult.
I was going to post in here the other day, and forgot. I went for a hike and bird watching with a friend from meditation and it was really nice. We'd never hung out before, but it was quite nice to spend time with her and get to know her more. It was fun.
That book about adult friendships...I know its at my local library, but I forgot to look at the name.
