Musician Sinead O’Connor claimed she is “one of millions” living with mental illness and dealing with suicidal thoughts in a video she posted on Facebook while at a motel in South Hackensack.

Dr. Phil McGraw opened his new season Tuesday with a wide-ranging interview with troubled troubadour Sinéad O’Connor, who discusses such topics as her abuse at the hands of her mother, how a hysterectomy made her come unglued and led her to attempt suicide (most recently in August of this year), and her infamous 1992 appearance on Saturday Night Live.

She said that while she was in the hospital trying to stabilize her hormonal situation following surgical menopause, his father put the child into foster care and her family left him there for six months.

“I lost the plot,” she admitted, describing her mindset at the time as “raging and angry … “What made me lose my mind was that they kept me from my most vulnerable child.”

How does she feel about her family now?

“I love my family and I don’t blame them,” she began. “It’s not easy for families of mentally ill people. We can be difficult. I don’t want to make out like I’m a victim. I give it as good as I get. Believe me, I was an (expletive) to my family. I thought it might be better if they saw (a video about) how I’m feeling, they’d relate to it. I…
