Erika's caller continued discussing his family conflict, saying, "It'll be a difficult process. My sister was never close to my mom, but she took to my stepmother immediately. My mom and I were always close, and losing her sent me into a real tailspin. As time went on, I guess my sister got tired of trying to deal with my mom and gave up on the relationship. When Mom died, my sister even lost touch with the family for a while because we just couldn't communicate effectively. I guess she didn't know how to be around us without having Mom there to fight with.
"But when Dad remarried, the whole family changed. Suddenly my sister was my stepmom's helper in taking care of Dad, and she used to hate dealing with sick people. In a lot of ways, my stepmom has been good for the family. She made my dad happy, and he became a lot nicer to be around. But we just don't agree on how to take care of him, and it's tearing us apart again."
