'I'm just not for this world': Heartbreak of Jim Carrey's ex revealed in notes written before she died

Heartbreaking notes left by Hollywood star Jim Carrey's ex-girlfriend in the days before she killed herself reveal her devastation at their split, as she said she was "just not for this world".

Make-up artist Cathriona White, aged 30, was found dead at her home in Los Angeles in September, having taken a lethal dose of a number of prescription drugs.

She and Carrey had broken up a week before her death, and a report from the Los Angeles county coroner has now revealed that two notes addressed to the actor had been found at her home in the following weeks.

In them, she begged for forgiveness and said she just did not "have the will" to "put the pieces back".

In one, signed off with the word 'Dewdrop', she wrote: "I've spent 3 days now in disbelief that you're not here

"I can go on broken-hearted and try to put the pieces back. I could, I just don't have the will this time. I'm sorry you felt I wasn't there for you. I tried to give you my best part."

A second note, addressed to 'Jim', asked for his "people" to sell her belongings and give the money to her family.

"I don't really know about burial or that sort of thing. You are my family so whatever you choose will be fine," she wrote.

"Please forgive me. I'm just not for this world."

In her final Twitter message, dated September 25 - three days before she was found dead on September 28 by two friends and Carrey's personal assistant - she wrote that she hoped she had been "a light" to friends and family.

According to the coroner's report, Carrey had sent a text message to Ms White a day before her body was discovered asking where his painkillers - understood to refer to prescription drugs Ambien, Percocet and Propranolol - had gone from beneath his sink.

The last activity on her phone was four days before she was found dead, when she had a three-minute FaceTime conversation with Carrey.

The drugs were later found at Ms White's home.

Her cause of death was given as "multiple drug effects", after a toxicology examination found propranolol, zolpidem, oxycodone and oxymorphone in her system.

Investigators heard from her friend Dennis Bradshaw, who said while she was generally "happy and upbeat", she could get "really down", and had described being "madly in love" with Carrey despite their "rollercoaster" relationship.

"She tied her identity to him and if she felt he (Jim) was slipping away, she would become depressed," the report said.

Another friend, Jenny Burpee, said she believed Ms White had taken an overdose of pills around two years earlier, after Carrey had first "unexpectedly" broken up with her.

Carrey, who described Ms White's death as being "hit with a lightning bolt", carried Ms White's coffin at her funeral in her Irish home village of Cappawhite, Co Tipperary, in October.

"She was a truly kind and delicate Irish flower, too sensitive for this soil, to whom loving and being loved was all that sparkled," he said in statement following her death.

"My heart goes out to her family and friends and to everyone who loved and cared about her."
