I had severe ADD as a child and now live ADD free. I was officially diagnosed as having ADD and now they say I'm fine. I can do anything, comprehend anything, et cetera. ADD may seem very real to you and it is. But it can be over come over a period of years with hard work and persverance. If you really want to change it, get rid of your tv and live your days in a repetitive pattern. Read constantly, and slowly, but I think certainly, you will overcome ADD.
ADD is a common postmodern affliction and is very natural. It may mean that you are ultra senstive which is a good thing. You just have to work through it.
