I hate being called lazy

I have severe ADHD, I have trouble focusing and getting work done on time, i’m so tired of people calling me lazy because of it, i’m not lazy, i’m trying I really am but nobody sees that. Just today in class I was working on this project were doing and I was thinking of what else to add and it was taking me a while cause I have trouble coming up with ideas (especially if it’s about smth i’m not very interested in, such as school work) and my teacher, in summary, tells me to “hurry up, you’re just being lazy”…the way I wanted to look at her and yell that i’m not lazy, I have a disability that makes it hard for me to finish work quickly. I’ve told her I have ADHD before, I’ve told her I’m not as fast as everyone else. Like trust me if I could change, I would, but I can’t. I swear everyone just sees ADHD as something that makes you hyper, when it’s literally a disability, buts it’s not classified as a learning disability so I guess that automatically means it shouldn’t effect school??? I don’t know if i’m being dramatic or not, I just can’t stand it when people call me lazy. I swear i’m not, I hate myself enough already, I don’t need other people reminding me how bad I am at basic tasks. Plus I feel like such an attention seeker whenever I try to explain to people that ADHD is a disability, I feel like since it’s so water downed in media and it’s pretty common no body takes it seriously.
