Cystic Fibrosis medical equipment

Hello, My name is Tyler kyle and I have cystic fibrosis. This disease causes mucus build up in the lungs causing frequent infections and overtime damages the lungs to a point where transplant is necessary. My current lung function is 23% and hoping a transplant will happen soon so I can restore my life to a point where walking across the house causes shortness of breathe. Until I am able to have a transplant I need a portable oxygen concentrator that my insurance will not pay for. I can only hope and pray that I can raise enough money for one so I can at least leave my home and not have to be worried about being winded and working harder than I need to be just getting a few groceries.
