WHAT IS WRONG WITH ME?

ok i have been feeling REALLY dizzy lately, and today when my mom and i were at kmart i turned around like 1/2 way not really fast and i got SO dizzy, i felt like the room was rocking and you know when your dizzy from twirling around and you step back? that's what i did i had to hold on to a rack. my mom has the same thing, but i'm 12.(my mom is hypoglycemic, am i getting that?)
