What region of the world are you in? There's help out there for you in some parts of the world. In the USA for sure. If you're in the US, ask to meet with your school district's special needs coordination / administrator. You may have had school-based speech therapy in the past. Obviously, it wasn't up to the task. It's time to get some professional help. They may be a good resource for helping you find effective treatment to improve your fluency. Ask your parents for help as well. Local Universities with Speech Language programs are another resource. Someone else also commented about some resources you can use to get help. Those are good resources as well. Growing up with a severe stutter, I never learned to ask for help. I always felt isolated. Like I had to do everything on my own. *You don't have to do it alone.* Ask everyone for help. Keep asking. You deserve help with this. People with stutters often fall through the cracks. We get inadequate speech therapy through the school system. Our parents are told "your child will grow out of it." All the while, the child with a stuttering problem suffers through it. With regards to your presentations... Ask that you be excused from the presentations. Or for a modified assignment. Work with your school counselor, principal, special ed coordinator. They, and your teachers, are all supposed to be there to help you. Ask them for help. And please, come back here. WE ARE HERE FOR YOU! If there is anything we can do for you, we'll do it.
