Is it ADHD...I forget everything and I am 18

one of the things that is not consistent with ADD is not remembering childhood, With the others, IF it is ADD, it is not so much that your memory is not working, more that you are just not that interested, and get easily distracted. When you say you forget where you put your phone, IF it is ADD, it is not so much forgetting, as that you were not concentrating on where you put them, and therefore did not know. It was not forgeting. If you walked in and said I am sick of wasting time looking for glasses, I will put them in a specific place, you would remember that place because you were paying attention, and in fact, putting things in specific places so it becomes a habbit is a good way to adjust. Also with not remembering what you just read, ADD people will not remember if they were not really interested, on the other hand, if it is something that really really interests you , you are more likely to have exceptional recall. Again it is not your memory, but your lack of interest, so when you read uninteresting stuff, your mind is thinking about something, you are not really reading it, just skimming, So you did not forget it, you never took it in to start with. If you get involved with something you are passionate about, you might be amazed at your ability to remember details I am much okder and only in recent years discovered my ADD. Boy it certainly made a lot of sense why my life had been so disorganised, But things of interest, I can become an expert very quick, as I recall every detail I read, do not even need notes. But I went on dexamphetamines, and I was stunned at my new ability to get organised, and get tedious things done that previously was not possible. One really important piece of advice,, If you are a thinker or an enteprenuer and you go into your own business, Get a good accountant, and manager to do all the bookkeeping and paper work, and all those tedious forms etc. I see ADD as a positive once you understand it and do things deliberatly more methodically. Like putting keys in same place, And if I am going to a meeting next morning, I will get everything I need and make a checklist, and leave it all at the door so I have to pick it up to get out the door. Good luck. It may not be ADD, get checked, I have a list of about 70 indicators that is used as one of the tests. I can send it to you, or you can probably download it from net. Also how are you feeling, and what was your childhood like, as a lot of what you describe is also consistent with depression. Do you have the positive attributes I mentioned. If not I doubt it is ADD. Many famous people are thought to have had ADD, including JFK Walt Disney just 2.
If I could be born again, and choose to have ADD or not. I would say yes for sure, I just wish I had known when I was young, instead of not knowing until in my 40's. It is not an illness, It should not be called a disorder, but Attention Difference perhaps. To many people it is a great help

This ADD runs in my family. My father had it, but he just died. My elder brother dropped out of high school in 9th grade because everyone thought he was the dumbest kid on the planet. My son has it too and has been on vyvanse and adderall. I was sick lately and needed some ginger which I learned to love as a child, but this is the crystalized ginger (like candy and awfully hot). I too stared out the window, could never pay attention or anything in school, but when my mother introduced me to crystalized ginger, I became an A+ student. I have one year of college and married in 1975 and had to give back 2 full-ride scholarships. I am an A+ student because I learned to love crystalized ginger. Give it a try. Better than caffeine anyday!
