ADHD is Attention Defisite (sp?) Hyper-active Disorder all that does to u is make u not sit still or have a low attention span...i have no clue how that would make u depressed or suicidal It's called Attention Deficit Hyperactivity Disorder and it doesn't directly. I did a research project on it for my Anthropology class this past spring, I'm no expert but I do know a few things. It basically makes your mind a tv where you can't control the remote and it keeps flipping from one channel to another, so you can't really focus on anything for a long period of time. There are 3 types of it; inattentive type, hyperactive-impulsive type and combined. This girl most likey was diagnosed with it as a child and we all know how kids are, they make fun of others so that they will be accepted. Some kids with ADHD are called lazy or slow and some really harsh things (which I will not say, as my best friend has ADHD) and they end up getting a very low self confidence. Maybe that's what happened to this girl? I just hope that she doesn't take it to far. There are alot of websites on the subject and some support groups, so if you want to learn something new research it. Ok that's my 2 cents worth.
