Here's an idea: if someone else has a problem, consider the idea that they can have problems too without invalidating yours.

Sometimes sharing that you have/had similar struggles does a few things:
A) lets them know they aren't unique to their situation (they aren't terrible ppl, simply bc they have a problem).
B) can provide a source of experience, if someone has survived such a situation already...can give hope to them, or advise
C) "we're all in this together" mentality, as a way of support
