ADD, but i honestly believe attention defeciet disorder doesn't exist. i was 'diagnosed' in kindergarten have been pumped with drugs such as ritalin, celexa, adderall, cylert etc since then until i stopped all together in 12th grade. struggled with a speech impediment from 4th to 10th grade. also struggled profusely in mathematics. in 12th grade i went to a new shrink, we discovered that its was NOT ADD all along, but rather a more serious and legitimate learning disorder known as dyscalculia. my ADD diagnosis had been blanketing an actual disorder all along. basically discalculia had been the source of my stuttering and trouble grasping concepts related to time, space, quantity, distance, and simple equations but we never ventured outside the ADD box.

moral of the story: ADD/ADHD is severly over diagnosed, often covering up a more serious problem.
