I know that feeling. I've been there, and I'm still there for the most part. Not sure if you've tried speech therapy, but that helps. Ultimately, just remember that people don't care when you stutter. No one remembers the details about someone else's life. If you stutter confidently, no one is gonna give you shit. If they do, maybe reconsider if those people are worth keeping in your life. If an employer rejects you because of your stuttering, then maybe they aren't a good fit for you. Fuck them. Things will work out. They always do.
