Jim Carrey must be feeling shattered and devastated after Cathriona White's tragic suicide. And, the latest revelation by the law enforcement has left him feeling worse as it has been revealed that she died due to a toxic drug overdose of pills that were prescribed to him.

The 28-year-old was found dead on 28 September by close friends and apparently with three bottles of pills on her bedside. The medication was apparently prescribed to a "fictional male" -- an alias reportedly used by Jim Carrey -- and White reportedly took the pills, including Ambien (sleeping aid), strong painkiller Percocet, and blood pressure and heart medication Propranolol, to take her life.

When the officials initially found the body, they knew it was a suicide case due to an overdose, but they didn't exactly know the combination of the drugs that killed her, reported Hollywood Life. The report also stated that the authorities are waiting for toxicology report to confirm that information.

Apparently, many celebrities use aliases for sensitive matters, but it's not clear how White got her hands on the Jim's medications and the cops will reportedly talk to the actor about the same. The report also said that White's had been suffering from severe depression her entire life.

Meanwhile, Jim Carrey will be taking care of the funeral costs and has apparently paid for Cathriona's entire family to fly to Ireland where she will be buried.

Recently, it was reported that Jim was planning a future with White and that their recent separation was just meant to be a break, reported Inquisitr. According to the report, the two were seen last seen together at NOBU in Malibu on her birthday and she apparently looked very happy. But, Jim apparently broke up with her on 24 September (five days before her suicide) and she wrote about this break up in her suicide note.

Well, it looks like it will be really hard for Jim Carrey to cope with this news.
