Sinead O'Connor raises concerns with new Facebook post

Sinead O'Connor is once again raising eyebrows -- and concerns -- with a post on Facebook.

On Sunday, the 48-year-old Irish singer wrote a long, troubling post, noting that she had "taken an overdose."

"The last two nights finished me off. I have taken an overdose. There is no other way to get respect. I am not at home, I'm at a hotel, somewhere in ireland, under another name," she wrote.

Local reports followed, indicating that O'Connor was safe and in the hospital.

But on Monday, the "Nothing Compares 2 U" singer followed up with another rambling, head-scratching Facebook post, addressing people she doesn't want to see again.

"Jake, Roisin, Jr., frank, Donal, Eimear, I never wanna see you again. 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? I'm sh** 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 fu** are you now??? Murderers. Liars. Hypocrites. All of you. You caused this," she wrote on Facebook.

O'Connor has four children -- three sons and a daughter. In August, she underwent a hysterectomy. A month earlier, O'Connor revealed that her son (she didn't say which one) had a "life-threatening medical condition."
