Paul Walker's mother has opened up about her son's death and how she has been coping since his tragic 2013 car crash. In a heartbreaking interview, Cheryl Walker talked about losing her son when he was 40.

Cheryl said she and her son had plans with his daughter the day the Fast and Furious star died. Walker and a friend were killed while attending a charity event for the star's organisation Reach Out Worldwide in Santa Clarita, California, on 30 November 2013.

"I had had a really nice conversation with Paul that morning," she said on The Dr. Oz Show. "He was in my home, he left to go to the event and so I was expecting him back in the early afternoon, evening. And we had plans with his daughter, too, to decorate a Christmas tree that night."

She said a family friend informed her about her son's death while she was alone at home: "I think I was in the kitchen and then I heard somebody come in and I looked and it was a friend of mine. Somebody that Paul knew, too. [A] family friend. And she looked like she just lost somebody, you know, she looked very upset."

"And then other people started arriving, including the two young men that Paul grew up with that were trying to get him out of the car," Cheryl added.

She revealed she has been finding it difficult to cope with the death of her son.

"I felt guilty for even feeling like that, but I really, honestly would wish that I didn't have to wake up in the morning," she said. "I would never have taken my life, but I really felt that way. Because when you wake up, you have to realise it's real and you relive it all over again."
