" Grocery shopping is hard? Responding to emails is hard?!? Going to the bank is hard?!?!?"
For someone with ADHD, it can be. The author mentions in her contact information that she does have ADHD so your situation probably doesn't compare with her's.
As someone who has had 4 younger siblings diagnosed with ADHD, and who has self-diagnosed with ADHD, I can assure you it is highly overrated as a mental illness. A cousin of mine has hyper-encephalitis with major retardation; that's a mental illness.
*I don't mean to say what you said is irrelevant... having ADHD definitely makes it harder to handle the day-to-day chores... but it doesn't put you in a category where you can't relate to other people about these issues. ADHD is more like a shift in cognition strategy than a genuine disability.
While I agree that there are far worse conditions out there, I'd like to point out that ADHD falls in a spectrum; while for many people it's a quirk that can go undiagnosed for their entire lives, for some it's an almost crippling disorder, especially when combined with common comorbidities like depression and social anxiety.
