Just had an online meeting with my tutor. He doesn’t know I stutter. I stuttered really badly in the meeting, and I don’t know why. The meetings before this were wayy better as I sounded like a normal person. He kept asking me if I was there and it was so frustrating not being able to say what I wanted to say. I even wrote what I wanted to ask him down. I ended up saying it was a wifi problem and he understood. Please comment some nice words or anything that can make me feel better.
