I have a long story for everyone but I really need some help because I don't know what to do.

I suffered a concussion in January while in a basketball. I don't remember it at all but they said what probably happened was I dove for a ball, where I hit my head, and then a girl landed on my head causing another impact with the floor. I'm not really sure though. I didn't tell anybody it had happened because I didn't want to sit out. It finally got so bad that i was failing almost every class because of very bad short-term memory loss. Then at practice one day I passed out while we were doing sprints. My coaches made me go talk to the trainer where she said it sounded like a concussion. She scheduled a doctor's appoinment for me with a concussion specialist and made me sit out the rest of the practices until i saw him.

I went to the doctor's and took an Impact Test to determine how bad the concussion had been. The average person usually scores in the 50th percentile-I scored less than 1% in every category. I was pulled out of school and sent home to rest. I retook the test five more times until I finally got a high enough test score to return to school. I got right back into school and sports like I had never been away. I did alright for a few days, then the symptoms came back. I would nearly pass out during every workout, get tunnel vision, be very confused, light-headed, and a very strange sensation where I essentially "white out". My grades started to fall again and my parents found out i was having problems-I hadn't told them. It wasn't as bad as before so I stayed in school getting assistance whenever needed but I wasn't allowed to do any sports. I was out of sports for four months total then i lied and told them I was fine because I couldn't stand being out anymore (I know it was a stupid thing to do).

I had been doing alright until recently-it's gotten so bad I'm rethinking telling them because I think something is seriously wrong. Here is a list of the symptoms I currently have problems with: 1.My memory is getting worse again 2. I "white out" during strenous workouts 3. I can't focus during class 4. I get confused easily 5. I have bad mood swings which can be from all of a sudden feeling depressed to literally the next second feeling hostile towards my best friends 6. Very tired all day 7. Tingling in my hands and numbness in my feet 8. Feeling like I will pass out again 9. Occasional ringing in my ears 10. Feeling restless like I have to move 11. Very vivid dreams 12. Some nausea 13. Sometimes I get very dizzy or the feeling that everything around me is swaying 14. Sometimes a bright light or very loud noise aggravates the headaches 15. Feeling like I'm floating 16. The newest and in my opinion worst is the headaches, I've had constant headaches since I recieved a concussion it just depended on how bad they were but recently I have been getting some, that after some research sound like ice pick headaches. They are very concentrated in one spot on the head and is a stabbing pain unlike anything I've ever experienced. In the research it sounded like it should happen once and then go away but for me it lasts a few seconds then a few seconds of relief then it comes back just as bad or worse and continues that cycle all day. I don't know if I should be worried about it or not. My parents are starting to notice my low grades and want to know what's going on. They might take me back to the doctor but I don't want to tell them what's is really happening (I don't want to sit out the rest of the soccer season).

Sorry for such a long post I just wanted to give all the information hoping there would be an explanation or someone else is also experiencing these symptoms. Thanks a lot for taking the time to read it and any help would be greatly appreciated. Any advice?
