Yes, there is a place called illness, and there are many paths that lead to that place. Many different people often unknowingly arrive at that place, from many different paths. It is like a pit or a trap.
Once in a while someone finds a way out of the trap, out of illness, and tries to share how they got out with others.
But since the different people took different paths to get there, backtracking that works for one person often does not work for others. Sometimes it does, but not always.
Ideally, for ill people the simplest way is to locate the superhighway of illness exit road. Sometimes the road is easy, othertimes one must use a machete and hack through the thick underbrush. And people who have exited the pit, some of them were not stuck in the thick underbrush, so they cannot know what others are experiencing.
The internet is limited in what a person can do or learn, and it can be frustrating to be trapped in thick underbrush saying "help, what should I do", and ten people answer but none of what they say and you are still trapped in the pit or whatever. Some say "go left and hack", others say "go right and jump" but none of it works, so then the blame goes to the machete for not being effective, or to the hiking boots for not working right.
