I felt this one.
That blocked nose with no sleep is no joke. Sometimes it is not even the sickness itself, it’s the lack of rhythm that makes everything feel heavier than it should. I like how you said cures don't happen overnight. That line hit me. We often expect quick fixes, but life doesn’t really work like that.
And this is the thing. All of it mounts up and "normal" is nowhere near normal. Everything is made harder.
