Sinead O'Connor continued to struggle with depression. Calling herself a "crazy b***h", the 50-year-old Irish singer/songwriter said in a new Facebook video that she's going back to hospital because she couldn't stand to be home alone even for 24 hours.

"It's so awful to be so crazy. A painful thing," she tearfully said. "I'm totally destroyed now again, I'm going to have to go back to the hospital, nightmare. This is unbearable, unbearable, it's absof***inglutely unbearable without my children, my loved ones." She added in another post, "Gotta go back to hospital. For fear will swallow all the stupid meds they've sent me home with. Such is life."

Just hours before the depressing video and message, O'Connor posted a more upbeat clip. She was seemingly relased from hospital and said she had "most beautiful week of my f***ng life." She praised the familiy running the Travelodge motel where she stayed. She also talked about the emotional issued she believed other musicians struggled with. "Let Justin be Justin, love you when you get in trouble. They didn't let you be a kid, f**k 'em," she said, referring to Justin Bieber.

Sinead O'Connor has been open about her battle with depression over the years. She's estranged from her family. While she stays in the States, her four children, Jake, 29, Roison, 21, Sahne, 13, and Yeshua, 10, live in Ireland. She's also involved in a legal battle with her former manager and ex-lover.

She was hospitalized earlier this month after sharing an emotional rant on Facebook from the motel where she stayed. "I'm all by myself," she said back then. "Suddenly all the people who are supposed to be loving you and taking care of you are treating you like s***. It's like a witch hunt." She added, "I'm a 5ft 4in little f***ing woman wandering the world for two years by myself."
