She was sexually assaulted in a back alley off Beach Avenue, Whitley Bay, at around 2.30am on August 2, 2009.
The ordeal has changed her life, and she said: "I don't even go in my back garden if it's dark."
She added: "When I came out of hospital I was in a blur. I had gashes all over my back, the tops of my shoulders and my head, face and jaw were swollen.
"I had black eyes and scrapes all over my body and I had damage to the backs of both of my eyes from being kicked so many times.
"My nose was broken and my mouth ripped apart from inside to out.
"Since the attack my life has completely changed.”
Following the attack police officers found her in a distressed state with serious facial injuries.
