I imagine most disabilities are like this, much worse for some, but it really frustrates me that to cope with ADHD we need to have a whole second job.

Make ToDos, exercise, take medicines, manage emotions, follow a whole check list of things to do to get your attention back to your work, constantly test and try new methods to see what works and what doesn't, handle the anxiety that comes with not being able to do work, constantly think about how you can improve something.

It doesn't help that the coping itself takes up valuable processing space that should have been in use for something more important.
