Welcome!! So sorry about the classes, how frustrating and discouraging! Do you happen to have insurance where you could go see an OT and maybe a Psychologist who specializes in education issues? RE the looking at socks as a child and playing by ear with music, maybe looking into vision therapy if possible as well? Honestly, if you need accommodations in school as long as do whatever documentation is needed, if someone thinks it's because you are lazy, then that's their issues not yours.

It sounds like you have a lot of talents RE longboarding, doing jumps and flips and music, speaking as someone who cannot play a single instrument or do anything that resembles a flip or stunt of any kind ;-) .
