I'm so sorry you're dealing with this. I don't have any magic advice that will help you talk with no problems. I think we all know that doesn't exist. And we've all felt how you're feeling right now. All I can say is no matter how afraid you are now, I promise it's not going to be as bad as you think. Just be you, and if you stutter, own that shit. If someone gives you shit, fuck em. I've had people laugh at my stutter for whatever reasons (probably just nervousness or they think I'm joking), and nothing makes them backtrack as quickly as "Sorry I have a stutter." Keep working with speech therapists if that's your thing, but just keep on keeping on. Nobody out there actually gives a fuck if someone stutters, and if they do then chances are they weren't going to stick around in your life regardless. You're gonna have awkward moments. Sooo many awkward moments. But the more you have, the better you get at handling them. You got this! Just be you and nobody is going to give 2 shits about a stutter I promise.
