I'm not even dyslexic but remembering which direction a letter goes in just on its own is lowkey so hard. I'd never mess it up in normal writing but ask me what direction the letter L or R goes in, and I'll have to think for an embarrassing amount of time. Or even worse, lower case D and lower case B. I do actually mess those up if I think too hard about them. Oh and I get N confused sometimes too, but that's just because technically Russian is my native language and the Cyrillic alphabet is all kinds of fucked up.
