Sounds like you are having some trouble getting some of the books I suggested. You might try this web site for more ideas. I prefer books cause its a lot easier to just pick up the book, but it does sound like you need more ideas. Scroll down through this site as several things are mentioned. http://www.ncpamd.com/adhd.htm#Attention%20Deficit%20Disorder%20in%20Children%20and%20Adolescents
If this works for you, I can recommended several more sites hopefully aimed at kids.
Keep working at it. And make sure that as you get help for him, you are also taking steps to take care of yourself. It sounds like you have a lot going on right now in your life besides the challenges with your child. Remember that children sense stress and know when something is wrong. Have you tried contacting any agencies that offer family support? The agency I work for offers support to the whole family when they are struggling with different issues. There is a lot of help out there if you go look for it.
