I'm a 28 year old writer-photographer, poet and politico. Born in Australia, I've lived in Manhattan, London and Philadelphia, and have been blogging, tweeting and advocating about mental health issues for more than three years. I'm your sister, your cousin, your friend; an old woman, or that kid playing in the yard across the street. Hi. My name is Kate White, and I'm 1 in 4. Haven't heard that statistic before? Then you should know that 25% of the world's population will experience a mental health problem at some point in their lives.
