In his final days Williams would forget his lines, suffered from a shuffling gait and would cry uncontrollably all the time reportedly. 

Makeup artist Cheri Minns said that, “He was sobbing in my arms at the end of every day. It was horrible. Horrible.” 

Minns reportedly suggested that Williams return to stand up comedy as a way of cheering himself up, but it didn’t work.

“He just cried and said, ‘I can’t, Cheri. I don’t know how anymore. I don’t know how to be funny,’” she said. 

We all still miss him and his comedy.
