I picked up a small rock earlier when I was vacuuming the store and set it on the counter to toss later. Fast forward, my boss comes in and sees the pebble and is like what's this? I was like oh shit sorry that's a pebble I found that I didn't wanna destroy the vacuum with, and apologized for my forgetfulness due to my, professionally diagnosed, ADHD. He then proceeds to sit me down and explain that ADHD isn't real and there's basically no such thing as mental illness and that I need to “train my brain” to remember better and “trick” it. Then he proceeded to give an example of how doctors distract kids when giving them shots as a way to trick my brain into remembering better (what?) Then he asks me how I study for school. I'm like dude what? None of that is making sense lol. And studying is also hard! I have to reread things 10 times before I absorb the info because my thoughts are rapid fire and before I know it, I didn't read anything and just watched the entirety of Shrek in my imagination. I chose not to argue despite his idiotic stance and shrugged it off for the most part, but it bothered me that he brushed it off and that it's basically my fault that I can't concentrate the best or remember every little detail. Also studying and remembering to throw away a rock I left on the counter are different!
Tl;dr my boss said that not only is my ADHD not real, but that mental illness isn't real and that it's essentially my fault since I don't train my brain to remember things better.
