Suicide on college campuses is a problem that’s difficult to tackle. As with mental-health issues in general, it’s not something most college students want to talk about. And that can lead to isolation and lack of treatment.

Tomorrow, more than 300 people will march on ASU’s campus as part of the annual Out of the Darkness Campus Walk.

Emma Wheatley is an ASU student and is the president of Ask.Listen.Save, a suicide-prevention and mental-health awareness club on campus. She’s also this year’s campus walk chair.
