Attention deficit hyperactivity disorder, also known as ADHD, makes it so I have a tough time focusing, and I am constantly active even if I am tired. This makes doing certain things a lot harder and other things easier. Things that are easier for me are things I enjoy doing, like video games, because I can hyper-focus on those things. Things that are harder are things I do not want to do like, like math, and my Brain just chooses to tune all of that out. I take meds that help me focus, but the problem is the current ones we take are the best ones, but they make me feel really sick when I take them. My doctor is getting us new pills so we can try them. Some strategies we use are 20-10.  You work for 20 minutes, then take a ten-minute break.  It's also helpful to get all the hard subjects done first while my brain is fresh.
