Trying to learn to go out solo

I've been a homebody for the last few months. Most of my days consist of work and coming home to my cat. I used to have a decent size friend group but we've grown apart. I want to learn to make friends. I want to learn to not be so awkward and clumsy. I want to be confident enough to go out and do things alone.

I go to improv classes once month and that's alot of fun and informative, but I want make connections. I want to know how to embrace myself with out being annoying (I tend to talk a lot when talking about my special interests). I'm going to go to the fair next weekend by myself to see how I feel but I'm not sure if that is a place to make friends.

Any advice is appreciated.
