Everyday my sister and mom get in a fight, not physical, but there's screaming from my sister and crying from my mom. My mom asks my sister to do chores or take some of her makeup off because she looks like a raccoon and my sister refuses. My mom keeps trying to get her to do it, nicely, and my sister starts yelling, screaming, fighting. It's so upsetting because my mom has fibromyalgia and chronic fatigue syndrome so the fighting makes her sick, and then she starts crying.
This has been going on all my life. 15 years.
I don't know what to do.
