The fallen star, best known for her role in rapper/actor LL Cool J's TV comedy series In The House, recently sparked fears for her health when a video surfaced online showing Campbell rambling incoherently in an apparent drug-induced state.
Her father Ellis Gordon, Jr. has now revealed Campbell, 32, is seeking professional help for her "illness" at an undisclosed location in an effort to "become whole again".
In a statement to Essence.com, Gordon and Campbell's grandmother Doris C. Moore thank fans for their support and call on devotees to "pray" for the troubled actress.
The statement reads, "Our hearts have been deeply touched by the outpouring of love that so many of you have freely displayed in the past several days about our beloved Maia C. Campbell. Our spirits have been lifted by your words of support and your acts of kindness and we have been encouraged to continue our efforts to assist our daughter and granddaughter to become whole again.
"As a family, we have been struggling with Maia in her illness for quite some time. We continue to hold fast to our faith and hope that some day she will realise that healing will begin when she decides to reach out and accept the help and treatment that have been offered to her.
"We all have challenges in life that we must face, but when compound problems such as mental illness and substance abuse are prevalent, it can appear that there is no way out. However, our sustaining faith and trust in God compels us to believe differently. We strongly believe that Maia will be healed.
"We ask that you not only pray for Maia's wellness, but also commit to understanding this insidious disease, which is devastating our loved ones and community."
