Full Story: PARIS JACKSON Leaves Suicide Note as She cuts herself With Meat Cleaver in An Attempted Suicide

Paris Jackson was rushed to the hospital early Wednesday morning after she left a suicide note and then cut her arm with a meat cleaver in an attempted suicide.

Sources with an intimate knowledge of the situation tell TMZ ... Michael Jackson's daughter called a suicide hotline and the person on the other end was alarmed enough to call 911.

Sources say in addition to cutting her right forearm, Paris had taken a large number of Motrin pills.

We're told once Paris was taken out of her Calabasas family house around 1:30AM Wednesday morning on a stretcher to an ambulance and then transported to a nearby hospital, she was placed under a 5150 psychiatric hold for 72 hours.

She received "numerous stitches" for the cut and as for the suicide note, we do not know what she wrote.

The Jackson brothers Jackie, Marlon and Tito just sent this statement to TMZ: "Thank you for the outpouring of concern and support for Paris. She is safe and doing fine. We truly appreciate you respecting our family privacy at this time."

Katherine Jackson's attorney tells TMZ ... "Paris is physically fine and is getting appropriate medical attention."

The lawyer, Perry Sanders, adds, "Being a sensitive 15-year-old is difficult no matter who you are. It is especially difficult when you lose the person closest to you."

Police went to Debbie Rowe's ranch to speak with her today ... presumably because she's been spending a lot of time with Paris, and knows her state of mind.

Debbie Rowe's lawyer, Eric George, tells TMZ: "We appreciate everyone's thoughts for Paris at this time and their respect for the family's privacy."

A source connected to the family tells TMZ ... Paris "threw a fit" last night after she was told she couldn't go to a Marilyn Manson concert.  We're told she ran into her room screaming and slammed the door.

A source closely connected to Paris tells TMZ ... she has "tried this [a possible suicide attempt] in the past" but "this was far more serious.  It was not a cry for help."  

On Tuesday night ... Paris posted some cryptic tweets, including, "I wonder why tears are salty?" ... and "yesterday, all my troubles seemed so far away now it looks as though they're here to stay."
