karina didn't want chris to be among them. doctors, however, are reluctant to medicate a healthy 12-year-old. but karina focused on the benefits of the drug while her sister worried about the risks. >> the hormones bothered me. i understand the point of them. but she went to so many doctors and you finally find a doctor who says okay we're going to do this. they are just so controversial, the drugs. >> doctors were not the only obstacle. karina's insurance wouldn't cover it because the treatment was considered experimental. >> we had to go through an appeals process. six months we're working on an appeals process. >> week after week, chris worried the medication wouldn't come in time to stop his breasts from growing and his period from coming. all he could do was try not to think about it. >> of course, in the back of my mind there were some worries. but i would, like, push them to the back and not think about it
