get caught in it vs get involve with it

I'm having a hard time "when to put salt" with this in terms of getting caught in other people's problem maybe one the reason for this is i'm bad at it. True, that maybe i have to deal with it but i don't want to face every battle. This is to save my energy especially for things i would say its nothing to do with my own problem. Most of the time i found myself getting caught in it. Is there anyone of you here already or currently facing this issue coz i wanna find possible solutions?
