For anyone that knows about stuttering?

So I have a speech impediment and I think ever since after high school when I talk to strangers they usually give me looks. It gets me really mad but obviously I’m yelling or starting fights. But it’s like people look at me like “what’s wrong with him” or something like that. Even my parents think they understand but they don’t listen luckily I have a speech therapist that understands and actually stutters but learned how to limit it. But if anyone has the same thing as me or maybe deals with anything else how do you ignore or deal with peoples reactions?
