I want to improve my stutter

I want to improve my stutter Hey, I’m 18 years old and going to college. I accept my stuttering and live with it, but I had problems with presentations in high school. I would often make the other students assign someone else in the group unless it was a personal presentation. Now, I really need to improve my stutter, but I haven’t found any resources online or in my area. I just want resources that helped you. Thanks! By the way, is anyone else tired of being called an 'introvert' when we can’t do anything about it?"
