Robin Williams called friend, a close actor friend, before he died.  It was a shock to the whole world when the 63-year-old committed suicide last month, but in a recent interview, Billy Connolly revealed that Robin Williams called his friend days before he took his own life.

Apparently, according to Sunday World, Williams has been regularly phoning Connolly, asking advice on coping with Parkinson's Disease.

In a recent interview with the Daily Mirror, 71-year-old Connolly revealed that Robin Williams called the friend and tried to say goodbye before his death.

Last month, the versatile and talented actor comedian was found dead at his San Francisco Bay Area home in an apparent suicide.

In his interview, Connolly, also known as Big Yin, said his friend's death had "still not sunk in", probably more so now that he has come to the realization that Robin Williams called friend before his death.

According to USA Today, apart from being a comedian/actor, Connolly has always had a lot in common with Williams. The two had known each other for over 30 years, and they had both been diagnosed with Parkinson's, a progressive disorder of the nervous system affecting movement of the human body. Therefore, Williams had reportedly always turned to Connolly for advice and guidance.

It now appears as no surprise that Robin Williams called friend before he took his life.

Connolly said Robin Williams called him saying, "He was diagnosed after me and he was on the phone a lot asking me about it," Connolly says in an interview with The Mirror. But phoning me for advice is an absolute waste of f***ing time because I don't have it."

"It broke my heart when he died. I was in Malta with my family and my children were all crying. They all loved him," the comedian/actor added.

Connolly also said, "He is a stunning guy... You notice I don't speak about him in the past tense? It's still not sunk in, I keep expecting him to walk in."

According to USA Today, Connolly said last month that he managed to provide Williams with some advice about handling the continuing lack in the actor's facial expression, a symptom of Parkinson's. Days before the suicide, Robin Williams called friend and thanked him for the tip.

Connolly said of the phone call, "He phoned me a week later, just days before it happened, and he said 'it's brilliant it's working.'" Apparently, the Connolly noticed Williams acting a bit strange that day.

Connolly also said about the call, "During the call he kept telling me he loved me. I said, 'I know'. But he kept repeating it, saying, 'Do you really know I love you?'. I was thinking, what the f*** is he on about?"

"After his death I thought, 'Oh my God he was saying goodbye,'" Connolly voiced out, realizing what it had meant.

According to the Daily Mail, Robin Williams called friend a lot of times before the suicide. Connolly said they compared notes on Parkinson's saying, "We used to talk about Parkinson's a lot. He would call me and we would compare notes."

In the interview, Connolly also discussed about his dealing with cancer and Parkinson's disease. He said, "The cancer is OK. They took out the prostate gland. Everything is fine."

"The Parkinson's, I feel the effect of it every day. It's better when I'm in a hurry because I'm less aware of it, but I refuse to be defined by it. I just get on with life despite this being another bump in the road," he added.

According to Sunday World, Williams' wife Susan Schneider only revealed that Williams had been struggling with the disease shortly after the suicide.

She said, "Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety as well as early stages of Parkinson's disease, which he was not yet ready to share publicly."

Robin Williams called friend since Connolly has reportedly been living with the condition for around a decade before it was diagnosed. On the same day, the comedian had also been told he had prostate cancer, to which he has been given the all-clear recently.
