Hey! First, I‘m truly sorry you have to go through this. It feels horrible when people you love don‘t respect your stutter. Second, I don‘t know how old you are and also don‘t know if you‘ve had any kind of accident, but a cronic stutter usually develops in between 2 to 6 years old. I‘d get an appointment with a neurologist if I were you, just to make sure this isn‘t a symptom of something else. Stay well! And try talking to your parents about how you feel about how they‘re dealing with it. I know it‘s hard, but being honest and opened really is the only way, trust me.
