teen angst...I hate you mom

Today my daughter thinks she hates me. Without realizing it I betrayed her trust. She told me that a friend was in a fight with her parents. She said she would share the situation with me later in private. I thought her sister might have some insight. I pushed her to share it with her sister. Summer and her sister are very different and over eight years apart. Summer is openly artistic, creative and expressive through her clothing and art. May is outwardly a conformist, she was always slim, preppy and very popular in high school. Summer sees herself more as an outcast, an iconoclast, a rebel. Summer sensitive and cries easily. She did not want to share her friends situation and bad became worse as I began to push.
