Jim Carrey's Late Girlfriend Penned Suicide Notes Long Before Death

Jim Carrey's late girlfriend wrote multiple suicide notes during their relationship years before she actually killed herself.

Sources tell us investigators uncovered several notes after Cathriona White's death in which she suggested she was going to commit suicide, but didn't. The first was in October 2012 -- a month after her father died and 2 months into dating Jim. She wrote about not fitting in this world and being "too messed up for anyone to really love." She also said she loved Carrey and apologized to him.

The second one -- written right after their May 2013 breakup -- accuses Carrey of giving her STDs and blames him for her suicidal thoughts. She wrote "my blood is on your hands" and "you pulled the trigger on me." Again, she did not kill herself.

Cathriona and Jim got back together as a couple 18 months later. They had a romantic date in Malibu, just 9 days before her fatal OD in Sept 2015.

The notes could be crucial in the wrongful death suits filed against Carrey by Cat's estranged husband and mother. On one hand ... it's clear she was upset about STDs in 2013. On the other hand, she got back together with Jim in 2014. It also seems she was troubled and distraught about several things besides Jim ... including the 3rd anniversary of her father's death.

The final suicide notes, found near Cat's body, mention heartbreak ... but not STDs. She said in one of the notes to Jim "You are my family" and left him in charge of her burial and estate. She did not in either note mention her estranged husband or mother.
