I was just diagnosed with ADHD in my mid-30s. To my fellow neurodivergent people, how do you cope with this work hellscape?

I've been “Smart but needs to apply himself” my entire life. Motivated when I wanted to be but could rarely find the motivation to excel at school and work. I decided to get tested after changing careers/getting more responsibility and just sucking at it even though I knew I was talented, and it turns out I had an undiagnosed condition my entire life.
