Jacintha Saldanha, 46, wrote three emotional notes revealing the anguish that led to her suicide after she was duped by two Australian DJs into believing they were royalty, the Daily Mirror reported.

In one, the distraught mum-of-two outlines how she struggled to come to terms with the prank call by Australian DJs Mel Greig and Michael Christian to the hospital where a pregnant Kate was being treated for severe morning sickness.
But in another she criticises senior colleagues at the King Edward VII hospital over her treatment after the pair had pretended to be the Queen and Prince Charles asking about the duchess's condition.
It is believed the nurse's suicide note has left her grieving family furious, with husband Ben Barboza understood to want an inquiry into the hospital.
A source close to Saldanha's family was quoted by the paper as saying: "One of the letters, which is the longest, deals with the hospital and is critical in its tone. Needless to say, Ben wants a full inquiry into what happened, and he wants to make sure the truth comes out. Within the letter Jacintha calls into question some of the treatment she received at the hospital."
Scotland Yard detectives are examining the notes, as well as interviewing Saldanha's friends, family and colleagues at the hospital. The family have been provided with transcripts of all three notes.
Saldanha's third suicide letter is more of a practical one which deals with her funeral arrangements.
Senior Labour MP Keith Vaz, who is working on behalf of her relatives, said last night: "The truth of this matter has to come out for the sake of her family".
