Ugh! This is definitely why there needs to be age or "category" separation in these types of settings. Some people are faking without trying... I agree. Everyone one is so eager to get a mental health dx to have something to blame or explain undesirable characteristics or performance, and when they get that dx, they cling to it.

I used I work in a medical office, and parents would bring their elementary school to high school-aged kids in for an ADHD diagnosis. They'd say their child's grades are terrible, they talk in class, don't want to participate in [band] anymore, and aren't doing well in the two extra-curricular sports they're in that they "need to" do for future college scholarship prospects; they're sluggish and don't listen well, and seem scattered. The kids would tell the doctor they felt fine and didn't want meds, and were just overwhelmed. The parents would counter saying they were overwhelmed because of ADHD.

They would demand medication and would not be satisfied (ie angry) without... The doctor would give the smallest amount of a non-controlled substance ADHD med, like 5mg once daily in morning, and send them home, ALONG with "prescribing" the kid drop a sport, thus get more sleep, and have parents let him spend more time with friends. Two weeks later, the doctor would check in with them...

"OMG, Dr. [Name]! His grades have gone up and he's so much more alert and happy! The meds have worked WONDERS."

...The medical staff would laugh at these people behind their backs, knowing the med would in no way cause the changes claimed, if he was even taking the med at all. And this scenario happens all the time. These parents and people with the types of mind sets disgust and frustrate me to no end! Whatever helps them sleep at night...? Erghhhh.
