Before she allegedly fed her only child a fatal dose of prescription drugs at The Peninsula hotel last month, millionaire pharmaceutical executive Gigi Jordan left a paranoid "suicide" note describing the villains she imagined were pursuing the 8-year-old boy and herself, The New York Post reported.

It's a 20-page schematic of her downward spiral into psychosis, left in her computer for cops to find after her planned murder-suicide in a $2,300-a-night suite at the tony Midtown hotel and spa.

Her plans were only half-realized, cops say. Her son, Jude Michael Mirra, died from ingesting some of the "thousands" of prescription pills found in the suite, cops say.

Jordan, 49, was found in the suite with her son's corpse. She claimed to have taken a fatal dose.

"Taking our lives goes against my religeous beliefs, but what is Gods will?" she wrote in the rambling note filled with misspellings, sub mitted to the court by her law yer yesterday.

"I pray he for gives me and at least Jude is in a better place then this one. It's over now God save us," the letter ends.

Defense lawyers submitted the note to bolster their request that Jordan be allowed to post $5 million bond and wear a monitoring anklet and be voluntarily committed to the psychiatric wing of St. Vincent's Hospital.

"If she could be in a less stressful environment, in a less chaotic environment, the chance of suicide is diminished," defense lawyer Gerald Shargel told Manhattan Supreme Court Justice Charles Solomon, who may decide the matter Wednesday.

Lead prosecutor Kerry O'Connell wasn't buying it.

The prosecutor noted Jordan's supposed Feb. 5 suicide attempt failed despite the abundance of pills in her Peninsula suite.

"She was in her room with thousands of pills at her disposal . . . yet Ms. Jordan was not dead," O'Connell said.

Jordan has pleaded not guilty to murder and has been held in a jail ward at Elmhurst Hospital.
