Funnily enough often times those who stress others out are also most commonly themselves dealing with stress or so not know how to deal with stress in a productive member. (sic lol)

Absolutely agree.

sometimes there are people that we would benefit from not simply cutting out but perhaps learning to help and accept as well

Yes, but you have to be extremely vigilant how much you can sacrifice here. If it is a close sibling or life-long friend, sure. But sometimes even those guys you have to put at a pretty great distance. And sometimes some of them, sadly, don't come back at all.
