You need to tell your parents and go to the doctor. This is a real concern, especially if it is an on going problem. The bending of the neck before the black out suggests that it has something to do with the blood flow. Stress on the carotid arteries or or the carotid sinus can cause blackouts, dizziness or fainting. The "shinning stars" also implicate that there is a disturbance of blood supply to the retinas in your eyes. These could also be symptoms of a neurologic problem, such as migraine headaches or seizures. Diagnosing online is not proper and would involve a lot of personal information. That is why I suggest you see a healthcare professional, and hopefully this gives you some insight into how important this is to get checked out.
Okay thank you :D
