The Centers for Disease Control and Prevention also said Thursday that people no longer need to stay at least 6 feet away from others.

Jennette McCurdy, who co-starred in Nickelodeon shows “iCarly” and its spin-off “Sam & Cat,” has written a book called “I'm Glad My Mom Died.” McCurdy tells about growing up with an abusive mother who she says pushed her into showbiz, encouraged her to starve herself and who insisted upon bathing her daughter into her late teens. Debra McCurdy died in 2013 from complications of cancer. It's taken McCurdy years of therapy to get to the point where she is able to not only share her story, but laugh about parts too.
