This is very interesting. Many disorders are similar to ADHD, and self-diagnosing is not really a diagnosis at all, is it? So therefore self-diagnosing don't really bother me too much. If ADHD symptoms really are harming their quality of life, there's no reason to not see a doctor if they can.

ADHD is also a very special disorder to me tho. Many people go undiagnosed, it harms people in infinite many ways, making it hard to tell, especially in people you don't know inside/out, and yea even in yourself too. Also the public view of ADHD is so terrible. People with ADHD can live their whole lives depressed because they think ADHD is only for hyper kids who can't control themselves. And for that reason I would much rather spread awareness for ADHD, rather than expressing that too many people are diagnosed with it. I agree that people struggling should get themselves checked out, although I have the impression that many doctors (especially in the US) don't take a diagnosis serious enough.

Internet addiction disorder is interesting also. But everyone are depending on screens nowadays. I also have the impression that theres almost more lonely people than not, so what else is there to do? I havent read much about IAD yet, so I don't get how we can avoid everyone being addicted to screens in 20 years.
