I agree with Karen. At first I thought it sounded like a panic or anxiety attack. It sounds exactly like mine used to be. Perhaps you also had an asthma attack, and the asthma set off a panic attack or vice versa. Athsma can begin at any age without any warning.

If your parents and coach were there, why on earth did they not get you to a doctor? ESPECIALLY if the coach was there -- in today's sue-happy society the school has a major liability for you if you got hurt during a game, and they are not going to just let you go home after any odd attack without being fully checked by a doctor.
