i did it!!!! after 39+ FAILED trys i finnaly passed the test!!!!

Sounds really horrible and hope you never have to cope with this sort of infection/illness again. I have not had covid myself, but do suffer from flu (which in bad cases, for me, results in bronchitis). That chronic coughing is dibilitating I know, your chest hurts for ages and I hope you will start to get some serious sleep very soon (lack of sleep is also extremely wearing, and makes healing slower).
Don't worry about being productive - just do what feels best for you until you start to feel that you might just be feeling a touch better.
Best wishes for your recovery.

I'm not sure what you mean... if I did something wrong, I'm sorry
And I hope OP gets better soon
