I promise you dieing is not the way to make things get better. I know you mean something to many people even if you don't see it. As far as the stuttering I know it's challenging. Every day I feel like I roll the dice and hope I can talk better than the last some days I can others especially when I know I have a crowd or something stressful I know I won't but I know at least the hope is something that keeps me going. Teachers can definitely help with building accommodations especially if you have an IEP and help building confidence in talking in front of people. I know I was lucky most of my teachers were more helpful than I deserve but I had to be the one to ask. Please keep all this in mind and do not for any reason hurt yourself, I've lost too many people to that and it's not at all something you want to put the people you care about through.
