If you can run a home, care for your children and hold down a job then you are very, very high functioning. Being able to do something with difficulty and effort is a world away from not being able to do it at all. Please take a moment to consider that most people with ADHD are not as high functioning as yourself.
You can either do things or you can't. Many people with ADHD or autism, when forced to sink or swim (ie, "suck it up"), simply sink. That's not because they didn't try hard enough, but because they were inherently less capable.
Most people with ADHD cannot simply "prioritise" as we lack the judgement of being able to guess how long thinks take, and being able to mentally multitask enough to predict outcomes to know which is the most important.
Good for you if you can do that, but you're still punching down on people who are more disabled than yourself. You're not better than people with ADHD who can't do what you can.
In terms of individuals on this thread being hateful and abusive about this man's actions: it is irrelevant whether or not he has diagnosable ADHD, the fact is that the way he is being described is identical to to the symptoms of ADHD, and to see that being described as "pathetic" and as if it is a choice is incredibly hurtful.
The fact that this man is constantly late in ways which affect himself should be a clue that his behaviours are not his choice, and likely not rectifiable without medication and outside assistance.
I never said that OP should be her husbands carer - in fact I specifically said she is not obligated to. I also mentioned her husbands lack of self-awareness about this problem is making it worse.
All I'm saying is that vitriol and judgement about the symptoms of ADHD is hurtful and damaging, to all people with the condition.
