the real question is do you want to go through life like this, with brain function getting in the way of your goals and relationships or do you want to do something about it?
whether it's adhd (i think it is) or one of many other possible disorders, the answer is to seek out docs and/or counselling that can help lead you to the solution.
meds will help GREATLY...why not take advantage of them and get your life a little back on track.
