This would be a form of Self Care. I did a post on Self Care and got only one response. I am interested to know if others have an answer for this post on other people's emotions.

I am still learning about self care so, I don't have much to provide for an answer here.

I think maybe remembering it's not about you, it's about them may help. Doing general self care things, like going for a walk, seeking your own social support, or other things that may distract your mind will make you feel better.

Boundaries are important. What I think you are talking about is an internal boundary. "This pain, although I can feel it emphatically and understand it, is yours not mine."
