Kristen Stewart says she feels miserable after her cheating stunt

Speaking for the first time after she had admitted to having a brief fling with married director Rupert Sanders, Kristen Stewart said that she is ''miserable'' and not sure when is she happy. Kristen said that she occasionally finds happiness when she is pushing herself ''to the limits,'' but otherwise tends to be sad.

''I'm a miserable ****! I'm not sure if I'm most happy when I'm comfortable and content or when I'm pushing myself to the limits. There are such different versions of happy. And I really appreciate both,'' theTwilightactress said. She told Marie Claire magazine: ''I'd probably go back to school, read a lot and figure out what I should do.''
