i tried donating last winter, i was 17, 5'3, and 109lbs. got denied saying i had to be at least 110lbs since i was a minor... went today, im 18, still 5'3, and 116.6lbs. got denied because i "dont meet the height and weight requirements for an 18 year old" and that i can donate when im 19? how is that not enough?🙁 im so bummeddd!!!!!!! got my mom to donate though, so thats something
