Mariah-and-Alison-Carey*Although Mariah Carey is living a good life, her 54-year-old sister is going through tough times as she pleads for the singer to help her get back on her feet.

In a video posted by The Daily Mail, Allison Carey, a recovering drug addict, is requesting any type of assistance as she fights for her life. Last April, she became a victim of a home invasion that left her brain damaged and seriously ill. Since the attack, Allison has been in and out of the hospital. As a result, she is dealing with mounting medical bills.

In light of her situation, Allison, who is currently awaiting brain and spine surgery, recorded a heartbreaking video to Mariah in an effort to receive help from her.

“Mariah, I love you, and I desperately need your help,” Allison said. “Please don’t abandon me like this.”

Allison’s video has struck a chord with her and Mariah’s brother, Morgan Carey, who hopes the clip will prompt Mariah to reach out and to help Allison as well as make amends with him. Morgan has admitted in the past that he and the singer have been estranged for many years.

Responding to Morgan’s claims that she hasn’t helped Allison, Mariah’s representative countered, telling The Daily Mail Online that her brother’s claims are far from the truth.

“Through the years, Mariah has spent hundreds of thousands of dollars supporting Alison and her children,” the rep said. “In fact, Mariah has supported her extended family for over two decades.”

Morgan has since fired back, saying that Mariah’s claims are untrue, she hasn’t spent a dime to help out their dying sister. Morgan went on to state that he his no problem in fully blaming Mariah for Allison’s current situation.

“Because Mariah has not found it in her heart to help Alison get the care she requires, there are times when Alison forgets or is unable to take her medication and this sometimes precipitates problematic behavior,” he said while pointing out that Allison’s mental health is starting to deteriorate. “Alison was institutionalized for observation after being found wandering in the street barefoot and partially undressed, causing the police to be concerned.”
