I have definitely been there. What my speech teacher person :0 told me to do is at the beginning of the year, send an email to your teachers saying that you stutter and what stuttering is and stuff like that. It is a little embarrassing, but it helps a lot. Tell them some things that they can do to support you. for example, I hate when I am in the middle of a stutter and other people like finish my sentence for me. Tell them not to do that. Also tell them that you dislike reading out loud and and to not take off points for that. Eventually, you are going to have to learn how to get comfortable with public speaking, so learn strategies like speaking slowly, etc. There are many great websites for that. Whenever you feel that you can't be successful about your stutter, remember that there are many great people who stutter. Winston Churchill, Elon Musk, Kind George the 6th, Vice President Joe Biden, Actor who played Mary Poppins, actor for Darth Vader. Good luck and stay safe
