set back

I found out my mom and sister had been fighting since mother's day and hid it from me because I was grieving over my husband. When I was a little girl my family always kept secrets from me. With all the loss I have gone though in my life I thought I would be treated like an adult. So I poured my thoughts into a email and sent a copy to my mom and one to my sister. My mom came back and said nicely put. My sister came back with nothing but venom. So I tried to clear up some things with her and it was just a big waste of time. So I washed my hands of her because she was causing nothing but a ton of stress I do not need. I just feel bad for my niece she has very little family members left and she is a only child.
