Neurological issues can't be helped. Like ADHD I could do some things that sucked all day every day, but checking the mail? Nah. Mowing the lawn, why? Like I have to do laundry for societal reasons. But I needed help to do the boring day to day shit that keeps you a "functioning member of society".

A lot of people have self control in one way but not another. For me, I became diabetic because my ADHD is like "meh, you're not hungry, no need to eat." Then I'd get lightheaded and "oh shit, I need to eat or I'll die, put quick calories in me NOW" causing my blood sugar to spike, then it'd normalize, then drop too far before I spiked it again. I never got fat, so in your mind I had self control when I really didn't. After research, meds and some talk with the doctor my diabetes is under control, and I'm eating healthier because berries are just as easy a snack as say a pretzel snack pack, or easier than ramen.

I'm betting there's some part of your life where you're not in control, so don't be so quick to judge on someone else's struggle.
