How to make people to speak about their handicap? Especially ADD/ADHD

We've built a homepage to help people suffering from ADD/ADHD by learning poems. The homepage is built for mostly the k8-k12 sector. (nice drawings, text for children, etc.)
But our stats are not as good as we expected. We found out that the reason for this is that people try to hide their handicap. They are playing the cool, learning the whole afternoon instead of admitting that they have troubles. They hide their problems even from their parents.
Even if they found our tool and getting better in learning, they gonna still play the cool, saying "Till now I was chasing the girls, but from now I will start learning..."
Because of this very reason, our homepage is growing very slowly... What could we do to make people accepting their handicap? What could we do to make people speaking about their problems?
For example: Peter has ADHD. I introduced him a new method, and it helps him. Peter's friend is Sally, whose sister has also ADHD. Peter won't tell his story to Sally, because he thinks having ADHD is embarassing. That means Sally's sister will not know about this tool, and in the end I have to personally show our tool to each and every child with ADHD...
Any good ideas how to improve my situation?

I agree with the comment from iluxa. I hid my ADD handicap all the way through my childhood, and was usually a straight A student because I demanded it of myself and my father demanded it. I know that it would have helped to get medicated. I'm medicated now and it helps a lot. But the excuse of a handicap would also have held me back significantly.

Also, the personality type of someone with ADD does not want to take a break to talk humbly about living with a handicap. We would rather just develop a little more ability to focus and move right on. I think trying to get an ADD or ADHD kid to listen while you tell them that they have a problem that they need to come to terms with is a losing battle. Instead, the idea is to grab their fleeting attention with your shiny toolkit that can help them do the things they want to do better, without getting distracted as much.

I didn't come to terms with the idea that I had a "handicap" until I had been medicated for months and finally took a moment to reflect. So I think your answer is to forget about getting them to accept their handicap. Instead, get them excited about the super-power of focus and discipline. ADD people want to be able to focus. We just want to focus on ALL THE THINGS AT THE SAME TIME.

So, in short, make it more shiny.
