Child is now spelled ADHD

Why do so many children in America get diagnosed with ADHD (Attention Deficit Hyper Disorder) and get prescribed pills to be shoved into their body? Pills, by the way, that only have to show positive results in 2 out of infinity trials. I don't know any healthy children that are not hyper or that can pay attention for long periods of time. I realize that there are children out there who legitimately have ADHD or similar disorders, but the illness is being way over diagnosed just to have an excuse to market and sell more pills. Or even worse, to try to sedate the child so we don't have to deal with their childish behaviors. Find me a child who is very mellow and can pay attention to something for long periods of time, and they are either medically or self medicated. Chill out with the mental disorders. And don't tell me they are legitimate and factual just because they are published in the DSM-IV. Up until DSM-III homosexuality was listed as a mental disorder, and if you believe this then stop reading my blog because you need professional help.
