Nash said she wears the veil "so I don't scare people. And sometimes other people might insult you."
She said she hopes to one day be out of the hospital and more independent.
"Before I was always really independent. I wanted to be alone. I want to be independent but I don't want to be alone anymore," she said.
Nash has filed a civil suit against Herold seeking $50 million in damages for pain and suffering. The chimp's owner claims that Nash was her employee at the time of the attack and is entitled only to file a workman's compensation claim, which would greatly limit the amount of money she could receive.
Nash told Oprah that taking care of the ape was not part of her job and she was scared of even being around the animal.
"I do remember going to feed him a couple of times," she said. "He was big and scary. He was huge."
Travis, she said, was Herold's pet and not part of Desire Me Motors, the towing company Herold ran out of her home.
"It was her pet that she wanted for a companion... If she had to rush out or couldn't come home, I fed him," Nash said.
Nash said the chimp was usually kept in a cage, but when it had been allowed outside as a baby, years earlier, had ripped the hair from her scalp, causing her to tear up and Herold to laugh at the incident.
The 15-year-old ape, killed by cops, had starred in an Old Navy television commercial advertising cargo shorts. He reportedly enjoyed surfing the Internet and could change the channels on the television using a remote control. The chimpanzee was sometimes taken out of his room-sized cage to eat meals sitting at the dinner table with Herold, and occasionally drank wine from a wineglass.
Herold said Travis was acting strangely earlier in the day of the attack so she gave him the anti-anxiety drug Xanax, but later retracted that statement.
Police at the time of the attack speculated that a previous bout with Lyme disease may have accounted for the animal?s reported mood swings.
