How did you accept yourself?

How did you accept yourself? I can't stop thinking about what could have been. Can't stop comparing myself with my peers who have achieved great heights. I keep running away from my stutter. I haven't even told my closest friends that this is something i struggle with. I manage to hide it by just not talking much. At work every time there's a new employee we have to do introductions. I try to run away from this. Pretend to go out, take a phone call, go to the bathroom etc. But this is suffocating. And leads to shitty life where im always on the run and nervous. I NEED people to think I'm normal. I had a lot of childhood bullies that would target my stutter. Maybe that's the cause of it idk. But i can't continue like this man
