You are not alone. I too was diagnosed with asthma after a mild covid case in Nov. 2021. I also have spasms of the diaphragm. Albuterol does help when breathing becomes difficult but, thankfully my need has diminished. I have been in pulmonary rehabilitation, which has been extremely helpful, and am finding that my symptoms have improved over time. I hope you do see a pulmonologist and want you to know that there is hope of improvement.
