Ik this feeling man. I have a very severe stutter, to the point that I've stopped answering phone calls. When i have to pick one up like from a teacher etc, they usually cut off b4 i could get 'Hello' out. Sometimes after that. And everytime i feel worse and worse. I'm so sorry that happened to you and i can just give u my best for future. I just wanted to share this so that you know you're not alone. Good luck for the future bro
