Why do doctors call everything a "disorder"?

Yes! I agree. I think that doctors are degrading with their terms. I have eight "disorders", but they aren't like me being a complete physco teen. I mean, most of my issues are ones everyone has, but because of my life circumstances mine are more severe. I hate when doctors label you with a disorder of any sort. I think it is stupid, because even if you are in the slightest bit functioning differently then a normal person, you are mentally ill. What is that? I mean, I don't even think you can define normal.
