The Nothing Compares 2 U star sparked concerns for her welfare on Sunday (29Nov15), when she wrote a post on her Facebook page, claiming she had overdosed in a hotel room in Ireland. In the post, the 48 year old accused her family of betraying and abandoning her as she deals with a sick child and recovers from a recent hysterectomy.

After O'Connor's fans alerted officials, the singer was found "safe and sound" and treated at a local hospital.

And on Monday (30Nov15), the singer returned to Facebook to take aim at her family members again, particularly some of her children, her sister and a couple of her kids' fathers.

"Jake, Roisin, Jr., frank, Donal, Eimear, I never wanna see you again," she raged. "You stole my sons from me. Then you had hypocrisy to come to hospital and then not be here when I wake and not pick up phone (sic)? I'm s**t to you. You're dead to me. You killed your mother. You stole my sons.

"You left me alone for twelve weeks! Why did I have to hear it was your hypocritical asses here while I was unconscious?? And now you're Gone and not picking up phone? You are child stealing murderers, I never want to see or hear from any of you again. Why were you here when you're the ones who put me here???? And where the f**k are you now???"

She concludes, "Murderers. Liars. Hypocrites. All of you. You caused this."

O'Connor has been battling with her son, Jake, and ex-boyfriend Lunny over the custody of her minor children, accusing them of illegally keeping her from seeing the youngsters. She claims they took her children from her after she became depressed following her surgery in August (15).
