If you ever sit on the internet and actually read all the characteristics of different mental disorders you will come to realize that you have atleast a few characteristics of them all. It doesnt mean you have that disorder though. Thats why its best to not even try and diagnose yourself or another person simply be reading things online or in books...the mind is a complicated thing and we all have our flaws that point to different disorders.
well then they arent one, but maybe they have some other mental disorder. If they go to a docotor they can be properly diagnosed and taken care of.
Then that person has some of the characteristics. Im not sure what your question is?
