My relationship with my sister is far from perfect. It's caused me a lot of pain. My best friend has two sisters that she gets along with beautifully, especially when compared with me and my sister. Her sisters take these relationships for granted sometimes, and it burns me up. Don't get me wrong. I'm happy for her and her family. I'm happy that she and her sisters don't have to experience the pain that I do. I know that it's wrong, but I get so jealous when her sisters take their relationships with my best friend for granted. They have everything I wanted, and they don't even realize it. I am jealous of the loving relationships in that family. I know I shouldn't be. I know that I should be happy for them. I know that I need to let go of the pain from my relationship with my sister. I just can't. Am I a horrible person for my jealousy? Also, do I allow my pain to affect me too much? I just don't know.
