I've found that the best way to get over these problems is just to grit your teeth and do it.
The human body was meant to be tactile, which means that you touch your environment. Man was meant to walk barefoot across the ground, touch things with bare hands, as well as smell and taste things.
I don't think it's add/adhd as much as it's a symptom of our sterile environments. We carry alcohol based hand sanitizers, wipe our hands with alcohol based soaps and don't go outside near enough.
But tht's just my two cents worth.
