Why does the black sheep become the black sheep of the family?

My family is small, just my 3 kids, my mother and I, we are all we got. I lost my home through foreclosure and was homeless for three weeks, sleeping in my car. My mother would not let me stay in her house but took my kids in. My mom had surgery and I took care of her when she was down and out. When she had surgery she did not want me present, one of her friends went with her instead. My mom had to have a blood transfusion after her surgery. She put me through hell. She would get on the phone and tell stories on me telling people I was giving her hot water to drink and all kinds of other lies while I was tending to her. My mom even turned my kids against me. I had a bad ear infection and my daughter would not take me to the doctor instead my mother had my daughter to take her out to eat and I had to drive myself to the doctor with a terrible ear infection.

My mom is now in rehab because she lost feelings in her legs. I do not understand how a mother could treat their daughter so badly. I have three girls and would never treat them how my mother did me. I use to visit her in the rehab until the staff there started watching me like a hawk. There is no telling what lies she told the people there. My mother did not get this way until my dad died a few years ago. After my dad died she got money and made some new friends and she changed completely. I get blamed for every bad thing that happens in the family. I love my mother but she act like she can not stand me. If it come between her fiends and I would she leave me out in the cold and she did. I am the black sheep and do not understand how I became the black sheep.
