So I'm finally almost done with my Master's thesis and about to hand it in and book a day to present. The thing is I have massive public speaking anxiety, and I'm really afraid that I would screw up. I have put over 200 hours into my thesis (and I'm very proud and happy with my work), yet I feel it's unfair that's the 1-hour presentation could affect half of my grade if I'm not good at presenting. I know I could manage throughout the presentation because I did many presentations before and I have got good grades, especially with practice but **my main fear is when they ask me questions about my work, I could really go mute or mumble words that make no sense because of my anxiety**, even if the question is so easy to answer. I had days where I used to skip the first hour of the class so I could avoid simply introducing myself, that's how bad it is. I tried to reach out for the student counseling in my school but unfortunately, she is no longer in the school and there's no successor. My advisor knows about my issue from the previous semester but I'm not sure if I should bring it up to him now, I really don't want him to think that I'm being lazy or weak.

I never took any pills before but I did see a therapist for a while, he has helped me overcome my hypochondriac panic attacks but not the public speaking.  
If anyone’s been in the same situation or feels that they could give me any advice, I would appreciate it!
