Im a non stutterer and you have all rights to tell me to fuck off as youd be right saying that I dont know what youre going through. But. Its hard for everyone. And there are solutions. Ask your teachers to not call on you to speak. Answer in text if you cant talk. You said that you have some secondaries which are visible. If smone asks for attendance switch on the camera and theyll see that youre there and trying to say what you want to say. And as for presentations, if your class knows that you stutter, theyll expect it. Yes they might laugh a bit but dont mind it. They arent doing it out of malicious intent. Most people automatically laugh when they see smone struggling with smth, like for example if someone isnt able to catch a ball after 10 consecutive tries and is very angry about it, bet youd laugh too. So dont take it as an offense from them. I had to give a lot of presentations before and its hard for most people. If you fail, just laugh it off and carry on. If youd like me to give some more advice for presentations just dm me. I have too much experience with them, but I dont want this comment to be too long. And last thing, online schooling won't last forever. It will end eventually. So theres Light at the end of the tunnel. Sorry for my English. Tl;dr:there is none. Just read the comment.
