I am leery to discount anyone's mental health struggles because often enough they are very real. But it can be galling to see very functional people blame the smallest imperfection on a condition many people find debilitating. ADHD and Autism are prevalent ones now, but it also is almost a cliche to call yourself OCD for a bit finicky. I think there's also an element of blaming your shortcomings in life on an incurable condition so it's not your own fault.
