offered me a pinky nail full of cocaine and tried to sell me out to a pimp she explained that the trauma she endured led her to often say I'm eternally 12 as she was still dealing with the impact of those experiences Mariah said she ultimately decided to cut Allison out of her life to avoid being an enabler according to Baker the estrangement was profoundly painful for Allison he said it stung because Mariah called Allison her ex- sister she used to babyit and take care of Mariah when that came out she couldn't believe that Mariah had done that because she already was not talking to her but then she kicks Allison in the teeth while she was already down Allison had battled drug addiction and wor worked as a prostitute in New York to make ends meet she was diagnosed with HIV in 1990

proxy for 9 years said that Allison had been sober for over 3 years but her health continued to deteriorate before moving into her apartment in Upstate New York Allison had been living in a facility where she was undergoing physical rehabilitation Allison often wondered if Mariah would ever reach out to her particularly in the final weeks of her life according to Baker Allison was barely conscious during her last two weeks Baker criticized Mariah's response to the deaths of her mother and sister saying the statement was self-centered it was awful because it was just all about her he remarked in her eyes it's all about Mariah and never anyone else if she would have cared about her she would have talked to Allison when she knew she was dying it's how Mariah has been for a very long time she will do anything to get attention and is always looking for publicity Mariah had also been estranged from her mother Patricia at one point in her Memoir Mariah suggested that her mother's jealousy of her success contributed to the tension in their relationship that jealousy comes with the territory of success but when the person is your mother and the jealousy is revealed at such a tender age it's particularly painful she wrote Patricia had been living in a senior care facility in West Palm Beach after Mariah sold the home she had bought for her in Westchester County New York in

very intelligent and very sensitive person who had a really rough time in her life baker said she had a lot of obstacles in her life starting from when she was very young and I don't think most people could go through something like that and not be affected Mariah called her an ex- sister which was a nasty thing to say and Allison never got over that she continued to dismiss her as if there was something she could do to change that no matter what she will always be her sister thank you for watching if you enjoyed this video please subscribe and turn on the notification Bell for more updates
