I'm 17 years old, female. I'm 5'7"-5'8" tall. I weigh 177lbs. I wanted to try exercisng everyday. (Like jogging, hip hop abs, waxing our floor, playing volleyball) But i'm sort of Anemic (Low RBC count) so whenever I do vigorously active stuffs, my heart starts to pump fast like palpitate or something, I feel dizzy, my ears feels like they're going to burst, I become very pale. Like dead pale, my vision blacks out and I faint.
