You sound just like me. I have not been diagnosed, but my daughter has (she is ADHD combined type). My problems in school were tossed off as my being gifted. I soak up information the first time I hear/see it, and don't see the point in learning anymore about it. I started this school year (sophomore in college) with a 4.0 and now it is down to a 1.5, because I can't get my head in the game. I jump from one thing to another in conversations. My friends get lost trying to keep up with my conversations, and often I do too. My room, well lets just say I think it has carpet. lol The only time it was clean was when I moved in. I have all intentions of having a clean room, just can't stay focused on one project at a time. It drives me crazy that it isn't clean, I have OCD too. I will start cleaning and then find something that isn't "perfect" in that spot and then have to get it perfect and it ends up being a never ending circle. Too top off all of that, I also suffer from major depression, complex PTSD, and have anxiety/panic attacks. I forgot where I was going with this. Oh yeah, I have to move my foot to get to sleep too. My brain doesn't stop, it is like the energizer bunny, it keeps going and going and going and going... Unless I take something to help me sleep, which is about every night, otherwise I don't go to sleep. I am quite the mess. I have been considering talking to my psychiatrist about the possibility of me having ADHD, but don't really want to be on more meds. I am on a total of 3 anti-depressants, metformin for PCOS (those I take all the time), and right now I am also on tylenol 3 w/ codine, naproxen, and anti-nausea meds(slightly allergic to codine) for my broken foot.
Sorry I am all over the place. I hope you find the answers you are looking for. Know that you are not alone.
