How do I start becoming better socially even though I have a stutter?

How do I start becoming better socially even though I have a stutter? So I (M21) Keep letting my stutter ruin my life. I don't try to talk to anybody, I don't ask anybody out on dates, I've never asked a girl for her number, I hardly try to make any new friends, I never approach anybody If they're cool and I think we could be friends, I never go out and do any social activities or hobbies, I pretty much just never live life because I'm worried of the social interaction with my stutter. I would like to start going to more hobbies and making friends and maybe even get in a relationship and find a wonderful girlfriend soon, but I don't know how I should become better socially. How should I quit avoiding social interactions? How do I quit being scared of people's reactions to me stuttering? How should I quit being scared and just approach people whether it be because I think we could be friends or maybe I want to ask for a number/flirt/ask going to date?
