Men in 20s

Men in 20s The most frustrating thing about having a moderate stutter as a man in the 20s is not having the ability to stand up for yourself and also being at the mercy of others being nice. How do I expect to lead in work/relationship if I can’t resolve conflict or even defend my self verbally and articulate my thoughts. Do I have to accept it and just be a coward. I’m tired of having to constantly allow friends/colleagues talk over me and feel minimised. It’s isolating and lonely.
