Every time someone say 'it's fine' or 'I'm fine'
this is what comes up to my mind

Also in self-analysis, if I use this word... I translate it in a rather opposing meaning.

Yea...not fine.
That word rubs me the wrong way, like some hate the word moist. My brother T used to say it with such disgust and finality FINE... I can hear him now, ugh.
