I was diagnosed with COPD Late stage 3 a year ago. I knew I had an issue with my breathing well over a decade ago, i kept trying to get a workup for my breathing difficulty, to no avail. I had my 1st flare up about a month ago & ended up in the hospital. As a retired RN I sadly underestimated how bad I was. Currently fighting another flare up, with my Dr out on vacation till the new year. Sorry, i babble sometimes. I don't know how long you've been handling COPD but a lot has changed for me. Other than breathing I feel the hardest thing was accepting the slow down and being forced to accept help when I was always the one to be the helper.
I sincerely hope your time in stage 3 is long and easy for you. God bless.
