Just got to say here, it's easy to pass by the quiet ones.

People can underplay how much trouble they're in or not want to disturb the others with their stress [I have tried to keep my varied meltdowns out of family view] until it's beyond overlooking.

Conversely, people can mistakenly believe that others are just fine [example: Medical practitioners underplaying black/female symptoms or claiming Othered people "feel pain differently" 9_9]
