Trouble Breathing - Shortness of Breath - COVID

I guess my Main Hangups are; damn doctors, and their nurses, don't give you any Aftercare information whatsoever! !You get that off the internet, yourself, or you don't even know how to lay to sleep, to keep from drowning in your own mucus...
The nurse manipulated my oxygen numbers to keep from having to "play with an oxygen tank" as an emergency situation at the office, and putting me on oxygen, so I had to "borrow oxygen" from a friend of mine that's a retired cop. In other words she lied, and did not want to do her job correctly, filled out the paperwork to benefit her! Anyway I'm out I'm tired man I'm sorry to complain to you guys I was mainly looking for information on how to actually get healed faster, and to possibly see if anyone here has had the same kind of treatment, or same symptoms after 5 months, Etc. THANK YOU JESUS AND THANK Y'ALL!!!!!!!
