*Oy Shiva is a trademarked sland on the Yiddish saying Oy sivah that I use frequently

Anyway, death. This year at my school we have had two tragic incidents, a suicide, and today a wreck that rendered a girl in unsurvivable brain trauma. Because it's a small program, we've only 300 students, it affects everyone massively. Personally, I dono what to do. Any suggestions?
