Feel Cut out

Hello, I am new to this group. I am not 40 yet but plan on being fabulous when I reach 40. I have a 13yr old daughter and a 12yr old step son and a 17yr old step daughter who is heading off to college this year. I have been doing a lot of processing about my relationship with my daughter lately. We shared so much love over the years. Over the past six months she has cut me out of her life. I am so sad about it. I will try and spend time with her and she looks at me like “when are you going to leave ?” She’s very defensive and getting her to do her responsibility’s is extremely challenging. Can’t even hear even the slightest advice. We hear “I know!” when we ask her to do anything. Even though she knows, it don’t get done. Everything is “unfair“. She is consciously doing the minimal in school to get a D so she passes and can qualify for the schools end of the year waterside trip. She ditched her best friend of many years to be popular. And yes it worked. She is now friends with the popular girl who was the bully that brought tears to her eyes the past few years. So I cry for my child I will never see again. My baby is gone. All I have hope for now is that we may be friends when she hopefully out grows being a bitch.
