You so crazy! No, really.

You know how some women are kind of crazy, but in a hot, sexy way? Well, this one sounds like she's just plain crazy:

A woman who stabbed her tied-up lover so she could drink his blood has been sentenced to 10 years in prison. Tiffany Sutton told Maricopa County Superior Court Judge David Udall that she was sorry for the incident and said she never meant to hurt anyone, but received the stiff sentence anyway after he called the crime especially heinous.

Sutton, 24, pleaded guilty to aggravated assault in August. She was arrested by Tempe police in February after she repeatedly stabbed her lover during an alcohol- and drug-fueled sexual tryst.

According to police reports, the victim, 46-year-old Robert McDaniel, agreed to be tied up during sex but became alarmed and asked to be untied when Sutton pulled out a knife and said she liked to drink blood. Sutton then attacked him, slicing his leg, puncturing his arm, shoulder and back and cutting his neck and stomach. When he escaped, she chased him with a pickax.

Now, I'm thinking Miss Sutton probably manifested some signs of instability before she tied up the victim (i.e. the alcohol and drugs), which leads me to believe he was something of a dumbass.

Now comes the least surprising part of the story:

Sutton's attorney, Elizabeth Houck, told the judge at Tuesday's hearing that she suffers from a personality disorder that causes instability and has taken responsibility for her actions, according to the East Valley Tribune. [my emphasis]

Personality disorder? Instability? No, you don't say! She also thought she was a vampire, which is not at all insane.
