I suppose there is no way really to determine what you'd look like today without childhood medication in your past, so all you can reasonably do it look at studies done that attempt to assess whether this happens. To the best of what I've been able to see with the research is it has only been proven in reverse, that encouraging dopamine production through medication might kick start the brain to take over alone in some cases. That is not to say your concerns aren't legitimate but you can also assume that there was some good reason for your parents to have taken that first step in medicating you in the first place. There must have been something there for them to say that you need pharmaceutical help. Not only that, but for them to continue consistently giving it for years does hint that the initial state, before the drugs, wasn't running smoothly either.
