The Sex And The City actress' dad Dennis passed away in February after contracting pneumonia following a lengthy battle with dementia.
She was at his side when he passed away and admits she tried to battle her grief by swiftly moving on - before accepting that she had to properly mourn his death.
Cattrall tells the Daily Express: "My dad had dementia and then contracted pneumonia. They call pneumonia the old man's friend and I think in some ways it was because he passed away peacefully. I was there when he went and I was so grateful for that.
"I was going to go to Central Park to let balloons go but I couldn't get out of bed. I was trying to be brave and I suddenly thought: 'What am I doing? My dad died, I should be able to cry.' I was beating myself up about not being able to get over it.
"Then I thought: 'Get over yourself and submit to what is really going on,' which was that I miss him, it's his birthday and I can't call him. There's no phone to get to him on and there's no way I can speak to him."
