Q. This is mostly for people who have ADHD/ ADD or know someone with it. How is it impacted your life? If you have ADHD/ADD, what type of an impact has it had on the people who are close to you? If you know someone with ADHD/ADD, how have they made an impact on your life?

A. ADD can be a little hard to live with especially if it's not being treated. Having ADD makes it hard to stay focused on one thing for a long period of time. I have to make sure that I pack plenty to do when i go to school or else i would never make it through the whole day in a good mood. It isn't all bad though, I'm really good a multi-tasking. I can be working on six different things at once and get them done in a timely manner, whereas if i was just working on one thing it would most likely take me the whole day to finish it. Hope this helps.
