coleman's lung transplant

my son coleman was born with cystic fibrosis which is a terminal disease that affects the lungs and digestive system. he is 15 yrs old and is depending on oxygen just to accomplish his normal daily functions. he has to do airway clearance 3 times a day as well as take multiple medications and breathing treatments everyday. he has never been able to live a normal life and do the things a normal child gets to do. he is at the stage of this desease that if he doesn't get a lung transplant he won't live much longer. he is currently on the lung transplant list and is waiting for a donor. we live in montgomery al and he is on the transplant list in houston tx. he is living in an apartment there with his mother while he waits. he has to be close to the hospital so when he gets the call he can be prepped for surgery in time. he will not be able to return home until he has the surgery. the expense of the apartment as well as all the daily expenses are overwhelming for me and his mother. i have to stay home in montgomery and work while his mother is unable to work and she stays with him in texas. just the expense to go see him is more than i can afford. its 12 hrs away and i haven't seen him in 3 mths. i'm saving every dime just to be able to go there when he has surgery. we have insurance but it does not cover the daily living expenses nor the apartment. the apartment alone is $2800 a mth and that is the cheapest one available. due to his immune system being weak he can't stay in the ronald mcdonald house or any of those type housing. i have already refinanced my house just to pay the bills. we are a proud family but we have ran out if options. i have set a goal for $25000 to try and keep him there long we enough for the transplant. after the transplant he will have to stay several more mths and will need to probably raise more money then. please help give coleman a chance for a normal life. this is the only chance he has at life.
