I lived in the South for awhile and they have a term for it; "poor mouthing". In other words complaing about their health problems. i have a friend with lung cancer, people come to his place and complain of discomforts. It makes him nuts.
Both my moter and my sister have copied my lifestyle and that makes me nuts. If I dye my hair, red, next time I see either of them, they're sporting, you guesed it, red hair. If I take up a sport or hobby, they do also. My mother oncw wrote a Autobiography, Forth Step, life history, whatever you want to call it,
I guess I should be flattered, but I'm not, I'm spooked, it was all about me. She took my inventory. So, yes, I can appreciate your frustratuion. It's enough to be in pain all the time, without having someobe trivialize it by claiming they are in the same state.
