That is terrible and I am shocked. Did you tell your parents or slp if you have one? Maybe they can talk to them and educate them on stuttering....thats it's not your choice. Its like if one of them would have heart disease...actually no thats different bc you have some control over that but you do not over stuttering! You could also try to or give them information to read, but I do not know if this would cause you more pain.
