I stutter too and I have a great job. I talk to people all day and yes there's some times where I have to repeat myself or talk slower but you know what? That's okay. I no longer allowed stuttering to dictate how I live my life and people are okay with it, and so am I. Until you accept that it's part of you, you will never truly be able to let it go. I do sympathize with you as someone who does stutter but getting a job is not impossible having one.
