Learning to live with COPD/Asthma

My breathing Condition and Respiratory issues started with getting COVID 3 different times. Since then, I have a lot of diagnosis thrown at me then taken back like COPD, Asthma, Emphysema and Chronic Bronchitis. There was some speculation of long Covid. All I know is my quality of life has been significantly compromised. I have been oxygen dependent for 7 months so far. I have severe muscle weakness, leg buckling which has now confined me to a wheelchair. My biggest challenge is lack to communication and agreement between different health care providers. The irony through all of this, testing has not been able to fully explain my symptoms. Prior to March of this year, I worked full time, enjoyed traveling and spending time with my grandchildren. Since March I have been hospitalized twice and in Rehab for 3 months and now oxygen dependent for 7 months now. If anyone can relate or have recommendations that would be greatly appreciated.
