Fear of going back to school

Fear of going back to school I’m a stutterer who currently has a masters degree and I want to go back to school for my doctoral degree. The one thing stopping me is fear of the doctoral capstone dissertation that requires an oral presentation to a large crowd. I wouldn’t wish the fears and struggles we experience as stutters when going through school on anyone and part of me doesn’t want to go though that experience again. I know I shouldn’t let my stutter hold me back but I already have people look at me like I’m stupid when stuttering and I believe it would be even worse at the doctoral level.
