I've gotten good enough that people send me their hardest managers, and I usually turn them around. But at the end of the day everyone walks off lighter and I drive home carrying all of it. I'm the person everybody leans on, and I can't think of a single person who asks how I'm holding up.
More people experience this than they realize.
You hold everyone else up, and no one is there to hold you.
