Billy was an average teenager who attened school, played quitar, listened to music and did many things like most other 15 year old boys.
However, nobody knew the Billy had poisons running through his body. He was born with a rare kidney disease where only half of his nephrons were working. The nephrons is where water containing wastes are filtered and separated from the blood. Therefore the wastes could not always leave his body.
All of his life Billy was sick. Although he did have adnormal health problems when he was a young boy the doctors failed to dianogse him. It was not until he was almost 16 years old when his mother took him to the doctor because he was constantly tired. His skin also looked slightly green and he had many cold sores. They ran some tests and after seeing a specialist they decided he needed a kidnay transplant because his kidneys were close to shutting down.
