It's a very good chance David is suffering from Aplastic Anemia. I encourage everyone to research this. He needs a bone marrow transplant, and could possibly be hospitalized for months or longer in this case. There is still some chance of leukemia or other diseases, but they are mostly convinced of this form of anemia. I appreciate, along with his family and friends, all of the people who decided to help and I still want to encourage everyone to continue to help spread the word any way they can. Thanks everyone!
