Is it my fault I have bad English?

I accidentally wrote, "could of" instead of "should have" and I got laughed at. Maybe my English is worse than I thought.

I've always struggled with the different tenses, in fact, I still get mixed up now. My punctuation isn't great and my spelling is awful. I'm using a word checker now because I don't want to be laughed at again 😕

I've got dyslexia and autism, so it's harder for me. Is it my fault? Does everyone do this? Should I take some courses? Or should I just calm down?
