My stutter makes me feel incompetent

My stutter makes me feel incompetent I have had a stutter since I was a child and I have managed to get through day to day life without it being obvious. Even while I had to present at uni, it wasn't an hindrance. Fast forward to the present, I am taking some courses. My stutter is now so bad, no matter how much I practice for my presentation, even writing scripts and memorizing what I have to say, it's still very obvious. I hate the uneasy silence in the room when I present, because everyone now knows I stutter. I hate that my head tutor always have to tell the time keeper to give me more time (this is done in secret), even before I start. I just finished a presentation now, and I feel so embarrassed. I can't even look around the room, even though no one cares that I stutter,I feel terribly bad. In my personal presentation, I feel excited to explain my findings, but when the actual day comes, I stutter so bad, I start sounding like I don't know my work. For someone interested in academia, I don't know how I will manage this for life. *I just came here to rant.
