Hi Kelly,
Such good news about your lungs! I hope both of them are back to full function soon.
Your situation has helped your brother--maybe even saved his life. It's not something many people can claim as a result of their run-in with OC. Usually, it's more like third person anecdotal help and not for the benefit of a person with whom you share parents.
I'll keep both you and your brother in my thoughts and prayers for great success with treatment, a divinely guided medical team, and a quick return to complete health. I'd pray for a group discount, too. But, knowing that MDA is a top facility and a "destination" CCC, I know that would be asking way too much for even God to pull off.
Take care and keep us posted about what is happening with you and your brother.
Sandy
