first, you must get your child properly diagnosed. ADHD could only be one of the symptom he have. He might have other mild disorder syndrome from autism.

My son is diagnosed with ADHD and asperger syndrome. Some kids have combinations of disorder. The reason to get it properly diagnosed is so that you could apply effective method in helping the child.

One thing you must accept is there are no cure for it. There are on therapies to make things better. For ADHD, sometimes food play an important role. Some ADHD kids will get worse when they eat too much sugar or chocolate or ice cream and so on. Try to check the diet of your child. If less sugar can make him less hyper, then it would be good thing to do.

Don't worry you are not alone. There are a lot of government and NGO societies that can help. I send my son to NASOM (national autism society of malaysia). They have nice people there who could help. Google for NASOM.

As for other people who doesn't understand the problem or ignorant about this issue. First, try to explain to them. If they still unable to accept then ignore them. It's your son and your child. Avoid listening to some old-wives tales of eating this or that medicine to help cure the "sickness". Lots of these people trying to take advantage of desperate parents.
