Literally physically can’t do schoolwork anymore

Idk if it’s a neurodivergent thing or smth like even if I want to do it I just don’t. It’s like I remember I have to do the one thing then I remember another thing then idk what to do first so I just do nothing? I’ve been back in school for like a month and it’s like I’m already burnt out like wth :(

It’s not even funny anymore cuz I don’t HAVE to go to school I’m technically done after last year but idk what to do otherwise so I’m just doing 3 more years and hope I have it figured out after that
