No matter how well you eat or how good your lifestyle is, if stress is so severe that it makes you lethargic, it has a negative impact. I couldn't distinguish between stress that helps me grow and stress that eats away at me. I'm reminded of my father's words that being around selfish people drives you crazy.
A group that demands one-sided sacrifice from one person and lacks communication cannot last long. Human relationships should be ones where both sides have something to learn and help each other.
And even if such a relationship comes with the best conditions, it's healthier to get out of it. Getting stressed a lot has made my facial expression worse and my health deteriorate. Especially, I couldn't sleep well, and my skin got worse too.
I think it's the feeling you get when you have to stay with someone you've come to dislike and lost trust in. If that person isn't family, there's even less reason to be together.
