As for her personal turmoil during her relationship with Balthazar Getty, Sienna told press she suffered a nervous breakdown due to the widespread hate she was feeling.

I got to a point where I was like, I will just run away. It was just breaking my spirits, and I had been pretty resilient for a long time. I was not able to leave the house and was living in a state of fear, when Im really a fearless person. I had a kind of semi breakdown and everything just became too much. It was cutting me up to the point where I thought it wasnt worth it. I thought, Either I try and take them on, or if I cant, I dont do this anymore. Things are calmer now. Im not rebelling against something every day anymore.
