i haven’t got a diagnosis for ADHD, but for the longest time i’ve been Kid B. used to fail at copying stuff from the blackboard to my notebook, sometimes having my notebook functionally empty that day, or sometimes not having enough because i didn’t write fast enough, and then get beaten up that day upon arriving at home and showing it and then being told by everyone that i don’t care enough and that it’s all fault of whatever entertainment i have at home (the console i used to play games in, the computer i browsed in, etc.).
got that drilled into my head enough times for me to start believing it myself at some point. delusion only weakening by the time i was living with my father and him not actually caring when i decided to put more effort in people-pleasing by trying to figure out how to write less to make it seem like my notebook has stuff written on it since i never figured out how to write text fast enough like everyone else in my class could.
this never went away though. in my previous job i still got told that multiple times, as well as having that repeated by my mother in the past year because of me not being able to get a job this far.
