The 59-year-old actor has been out of the spotlight for several years after suffering a stroke and brain haemorrhage in September 2001, but is currently seen in Steven Soderbergh's new TV drama "Mosaic" as murder victim Olivia Lake.
"I absolutely felt insecure. But I certainly didn't want anyone to think I did. I was asking myself, 'What's going to happen if I can't do it? What's going to happen if I fall apart?'" Sharon told Grazia magazine.
The actor said she was particularly nervous because the stroke left her with memory problems.
