Stress

Stress Hello, I'm in high school and I have a speech block. Last Friday one of my friends miss spoke and just said"you be stuttering too man" not even something bad but just the fact my friends recognize I stutter stresses me out and I don't know why. I have a lot of anxiety even tho I don't stutter all too often but can someone give me some advice on how to not stress out? I'd appreciate since I don't stutter when I've got no stress and talk chill.
