thanks to two of you that helps alot and i will try what you said and see if it works
Since this thing came back up, I thought I'd add one more thought to it. Armag, could be if you could see a neurologist, he can run some rather quick tests to see if you do have some sort of brain deficit, which has to do with asking you a series of questions, more questions, and more. Then from your answers, they can tell if you have a brain problem going on. But once again, I think if you went to bed earlier, since you have to get up so early for school, and exercise regularly, you MAY notice your concentration is better, and so no need to see a neurologist, which your family doc can refer you to. One more thing, too, that I wanted to mention is, along with taking a vit/min supplement twice a week, you should get enough proteins in your meals, with eggs being one of the best. And don't skip meals, always eat breakfast, lunch, and dinner. Let us know if our tips help you in a few days!
I agree - it's probably normal. Rather than having something going truly wrong, you are just distracted and not absorbing the information you will need to retrieve later.
At your age, the main investments you need to make in your health are to eat right, exercise, and get enough sleep. Don't hang out with people who are interested in drugs. Even marijuana will cause problems with memory and performance. I honestly prefer the high of exercise and relaxation after working hard.
With you, chances are very good that since all teenagers need lots of extra sleep, which has been proven by lots of studies, that COULD BE you are not quite getting enough sleep, and/or you are not getting enough DEEP sleep or REM sleep (where you dream). So, I'll offer a couple tips to help you sleep better, in case it might help your thinking better. Exercise is just about the best way to sleep good at night. If you wear yourself down physically, when you hit that comfortable bed, you'll pass right out. It's good to get built-up tension from daily stress out of your body, and exercise to where you break a sweat about five days a week is how you do it. Second tip is DO NOT eat junk food or drink caffeine sodas for at least three hours before your bedtime is. I go to bed about 10 or 11, so I stop slurping on my drink or eating after about 8. Actually, if I eat a good dinner at 6, I really don't get particularly hungry the rest of the night, and usually will only have one caffeine-free soda poured into a glass with ice. One more quick item, take a name-brand vitamin/mineral supplement twice a week, and also drink plenty of water, around six glasses a day.
Keep in mind, too, at your age, there are some brand new "adult" hormones sugrging through your body uncontrollably, and it can really DRIVE a person and almost make them crazy, because in the beginning, they come out in big surges, and then flatline, and off they go again. Eventually the whole thing settles down, in the late teens, and you become a regular person again, you get used to the hormones. Just be aware of it, if you feel a little sideways, not yourself, a real space cadet, it's likely sleep, exercise, and hormones. So, not to worry, you will not become a zombie in the near future. You have many, many long and beautiful years ahead of you. Study hard, go to college, take up lots of physical activities and get really good at one of those, like I think Tango dancing or Salsa is really neat, I used to take dancing lessons. Some people really like tennis. Others run like crazy people! They get into marathons, wind up on a bus going to Boston for their marathon, and the Lord help you, even to NYC for an extreme marathon that NOBODY in their right mind should do. And one of the best exercises and one of the most beneficial is martial arts, talk about a workout, so you could maybe join one of those, I liked ju-jitsu because it uses the enemy's force against them (rather than karate where you punch people in the head).
