I’m so pleased that you are recovering Henetha. It must have been very scary for you.
I can understand the “plodding on” aspect - I think many of us do this as we don’t want to make a fuss, or think “it’s only a cold, usual at this time of year”, etc, etc. We are constantly being told how overstretched the NHS is, aren’t we and I think we think what we have is trivial and will get better, so no need to make a nuisance of ourselves.
I think what your situation highlights, though, is that any cough, breathlessness, etc that doesn’t go away after a few days should be investigated further.
Take good care of yourself, Henetha, have plenty of rest and I hope it won’t be long before you are back to normal 💐.
