A little perspective goes a long way. Sometimes, things just seem bigger, because they are close to you. Everyone is the same. No-one is different in the first place.
What different people do next can vary widely. It can be difficult to step back and gain perspective.
A small(ish) thing can feel much, much bigger when it seems like it is the only context of the moment. Yet, when you take everything into account, it might be rather small.
Find someone to talk it through with. Someone supportive, without a ‘fix-it’ mentality. Someone who listens. Someone who lets it be about you, rather than about them.
Just speak it through, make sure they understand the rules. Just to listen, really listen, to you. Getting it out of your head verbally, helps so much, so often.
There will be solace and a better understanding for you.
