In her Facebook post, which was shared earlier this week and later taken offline, Sidney claimed her mother was abusive.

"The reason I do not live with my mother is not because of my dad, it is because she is mentally/verbally abusive and not a mother to me," Sidney reportedly wrote. "For the past two years I’ve been asking her to stop treating me badly, to stop doing embarrassing and talking about me on the show, and to not use my siblings and I as storylines. Clearly she hasn’t followed through with anything that would have made me go back to her house."

"If she really wanted me back in her life she would have taken responsibility and changed two years ago when I told the first time what was causing our relationship to suffer," she added.
