@sophia I feel like you've just said what I've been trying to explain to others, including my parents, for a few years, but worded in a better way. I'm not a wheelchair user, but I should be, and I get "the looks" constantly for sitting down wherever I can, needing to stop often, or I just get straight up harassed by people above me, dorm caretakers, teachers, even if they are fully aware of my problem. "It's inspiring that you do art and manage to sit for 8 to 9 hours, even if it brings you immense pain", paired later with "you are just lazy and don't try hard enough. Just take painkillers" making me feel like I have to overwork myself just to be treated like a human and not something that just "isn't good enough".
I really want to thank you for posting this here. I often feel like maybe my experiences are only mine or I'm overreacting, but seeing other disabled people share that (terrible) experience just gives me enough strength to push on and still do what I love most, despite not my disability - but everyone around.
