I definitely think it was indeed my mom's fault, but I felt guilty when I was younger. I think my sister truly hated me because of my mom burning her for something that I did wrong. I verified with her recently that she really did blame me for it. It also didn't help that my mom praised me in front of my sister, but only when I wasn't there. She also praised my sister in front of me when my sister wasn't there. She put us against each other.
