Ervin ventured to obtain roles as an actress but gave up on the idea when she was constantly offered roles as an alien or monster. Later she studied law and exercise physiology. Tired of the office life that she had pursued and unhappy with her weight, she joined a gym but strived for an unrealistic size 0 physique that almost resulted in ending her life. She developed a healthier body image and became a fitness trainer.
Ervin underwent sex reassignment surgery in 2004, completing her transition. In interviews, Ervin has talked about the problems of being a tall woman. Other topics she has addressed include her troubles growing up dealing with teasing in high school, family problems and her modeling experience.
