Jacintha Saldanha -- the London nurse who killed herself after answering a prank call from two Aussie DJs -- reportedly had a HISTORY of failed suicide attempts.
Saldanha tried to take her own life TWICE in the last year alone, according to The Daily Mail ... first by ODing on pills last December, then again nine days later by attempting to jump off a building.
According to the report, Saldanha spent several days in an intensive care unit to recover, underwent psychiatric treatment and got scripts for a slew of antidepressants.
It changes the complexion of the now-infamous DJ prank involving a pregnant and hospitalized Kate Middleton. Being the straw that broke the camel's back is way different than what everyone first thought after the nurse hanged herself.
