Trouble Breathing - Shortness of Breath - COVID

They put me on the strongest IV antibiotics they had in the hospital, 5 different kinds, broad spectrum, then 2 kinds for 2 weeks after I got out. God Blessed me with insurance AFTER I got out. When I got out, they had me on oral form antibiotics, for almost 2 weeks.... That DIDNT DO IT.. They kept me for 3 Days, the pulmonologist said I could go, but the internal medicine doctor wanted to keep me... thanks to the prayers of My Friends, and my Mopar Family here, I was released, so I could go actually sell a small job, and We could keep the lights on at least! With the blessing of the insurance, I was able to see a pulmonologist, who prescribed me Levaquin, which is known to cure the plague, and inhaled anthrax, it's normally done for a 5-day course, I took it 15 days.... I'm still coughing up green and yellow, fluorescent looking crap, from deep down in my lungs, when I got out of the hospital it was Labor Day weekend... I'm not crying, I'm just wondering if+ anyone knows any homegrown remedies, to help try to make healing things further along! I know for a fact, if the first two hospitals, would not have mis diagnosed me, I'd have gotten antibiotics, and I would not have been as sick as I was before I got properly diagnosed by a decent Hospital! Thank you all for looking
