Grills said she began getting online messages and threats. "They would tell me to kill myself and save everybody the trouble."
The last year and a half have been difficult, Grills said. She was hospitalized after she attemped to commit suicide, and she says she hardly ever leaves her house.
ABC News contacted lawyers for Lori Drew who said they stand by their original statement: "Lori Drew did not create or direct anyone to create the Josh Evans MySpace account. Although she was aware of the account, Lori Drew never sent any messages to Megan or to anyone else using this MySpace account."
Grills said she is angry at Drew, who she once viewed as a mother figure, for making her the scapegoat.
"I have a lot of anger towards her for making me feel like crap," she said. "She had -- basically she was trying to make me feel like it was my fault and make me deal with everything."
Grills said she is speaking out now in order to get the real story out to the public.
The message she wants to get across, she said, is "that I'm not heartless. I do know what I did and I take responsibility for it every day."
