Los Angeles, Jul6 (IANS): The suicide note of Cathriona White, actor Jim Carrey's former girlfriend, who took her own life shortly after they broke up last year, has emerged.

The Irish make-up artist passed away in her home here last September after overdosing on prescription medication and was found with a suicide note for the actor.

The suicide note details how White felt after she and Carrey ended their relationship, reports tmz.com.

She also apologized to him, saying she had "tried to give you my best part", and let him plan her funeral.

"I have spent three days now in disbelief that you are 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," she wrote in the letter. "I'm sorry you felt I wasn't there for you. I tried to give you my best part".

She asked him for forgiveness, writing "I'm just not for this world".

Prior to the split and her death, White and Carey were reported to be dating on and off throughout their three-year relationship.

A toxicology report said that four prescription drugs were found in her system when she died.

Some of the drugs appeared to be Carrey's because police found on her phone at the time a text message from the actor, who asked her if she knew "where his painkillers went from under his sink".
