Seven summers ago, a phone call upended my life. I was playing SingStar at a friend’s house when my sister called me sobbing. She had just turned 21 the day before, and our small family had gathered at our apartment to celebrate her. I’d just come home from summer school, and was planning to spend the next few weeks with her and my mom before my junior year of undergrad. So, all was right with the world. I couldn’t fathom what had changed in the past 24 hours, what could have turned her joy into pain so quickly and decisively.
