The doctor said it could be my brain or my heart. Or it could have just been just from working out hard, not getting enough water, and not eating a snack before class.Either way, I'm hoping that it's nothing. Telling my dad and H that I had to see a cardiologist and a neurologist made me cry. And I need to call my mom to tell her as well. The brain part scares me the most. The thought of being like my MIL for the rest of my life is horrific to me.
