Sinead O'Connor isn't holding in an angry Facebook post aimed her family after the Irish-born singer went missing in a Chicago suburb for more than a day before being found safe by Wilmette police on Monday.

O'Connor went for a bike ride early Sunday morning and did not return, prompting an unknown caller concerned for her well-being to alert authorities.

Sgt. Michael Robinson of the Wilmette Police Department then issued a check-for-well-being alert and found O'Connor to be safe and sound on Monday afternoon.

O'Connor, who has a history of mental illness, later took to Facebook write a open letter to her first husband, John Reynolds.

"You tell that evil son of ours that a person who suffers from two fucking medical conditions of which the symptoms include suicidal compulsion isn't being manipulative if while he is being a f-----g chauvinist bully like his grandfather they say they're going to or feel like killing themselves. You all abandoned me FOR BEING SUICIDAL," she wrote.

In November, O'Connor posted an alarming Facebook post saying that she had taken an overdose in a hotel room in Ireland. The Nothing Compares 2 U hitmaker was later found to be safe, as previously reported.

"Every one of you had better pray I die. Because I'm suing the fucking lot of you for what you've done to me if I manage to live through it," she continued in her open letter. "None of you will ever see me again because of what you've done. If I manage not to kill myself, you'll be paying the medical costs which have been and will continue to be involved with that, since you were and remain the chief co-ordinator of my total psychological and emotional destruction."

"I will see you all in court. I want damages. I have been unable to work. I have lost last year's income and this year's. I have had enormous medical expenses, and enormous trauma because of your torturing of me," O'Connor added.
