I'm glad you quit smoking as well!
quitting smoking didn't cause your UC.....it nicely masked your symptoms, however. Great it's under control at this point.
Hope you're able to use meds that will help give you relief from the PH and COPD.
Yes, life and we are fragile. Living it to the fullest is certainly subjective. Making it through a day can be a huge accomplishment for some...
Hugs,
