Re: Adult ADD - shock discovery
I was also shocked as an adult when I learned I had ADHD. Still, being diagnosed and treated eventually let me finish college and improve myself a lot.
I took prescription medicine for a couple years, and it made it easier for me to learn how to pay attention and manage my life better. More importantly, I saw a professional ADHD coach who taught me how to use a day planner, manage my school assignments and advocate for myself. I currently do not use medications for ADHD, it was something I needed only for a relatively short time. (Other folks find it is best to take the medicines long-term, and some manage ADHD without any medicines. It's your choice to make.)
Find a psychiatrist who deals with ADHD a lot, for yourself and your child. Treating yourself AND him is the best way to help him.
