Robin Williams' rehab friend has revealed that the late actor told her that he wanted his death to be quick along with being clean and sober.
Teresa Cohen asserted that the 'Mrs. Doubtfire' actor dreaded dying while high on drugs or alcohol, the Daily Star reported.
Cohen said that Williams cried when he told her his greatest fear was relapsing and he might die early because of excessive drinking while his family watched helplessly.
She continued saying that the late 63-year-old actor did not want to die the slow, painful death of an addict who made everyone around him suffer too.
Teresa added that Williams told her that he was always pleased and proud to meet fans but felt under constant pressure wherever he went to 'wear a happy mask' and put on some kind of crazy performance.
