You never know what someone is going through. Therefore, a little more kindness, patience, and #love is needed.
I would add -
telling someone "but you look so well" or
"there's hundred's worse off than you" or
" so-&-so has pain but she still works"
we are all individual.
one person's illness, anxiety, depression, problems or pain does not diminish yours.
there can be no comparisons.
it's not a competition.
