Cassidy Lynn Campbell broke down in tears Friday night when she learned that she had been crowned homecoming queen but was born male.
The transgender senior at Marina High School in Huntington Beach, California began taking hormone blockers and estrogen injections prescribed by an endocrinologist and made the transition to living as a girl.
She decided to run for homecoming queen, in part, to make a statement.
"If I win it would mean that the school recognizes me as the gender I always felt I was," Cassidy, 16, told The Times before the election.
"But with all the attention, I realized it's bigger than me," she said. "I'm doing this for the kids who can't be themselves."
She succeeded in a big way!
