That’s terrible. You must have been one of the first who got Covid-19 so they didn’t even know to test you for it.
I hope there are treatments that can be done to rebuild your lungs. Maybe some alternative therapies. And, of course, prayer. May our Heavenly Father heal your lungs completely.
By the way, I never even heard the expression “cracked glass lungs.” That really sounds bad.
There are pictures of it on-line. It is not the proper medical term, but a colloquialism that exemplifies the damage done through COVID scarring.
