Ouch, that sucks big. I mean, c'mon people! Depression does not involve violence! Use your heads, when you hear 'depressed', do you think of shootings or do you think of someone slumped in a corner writing bad poetry? (not to insult or imply anything, just- meh)
My cousin has depression, as does her mom. For both, the times that they've been able to cope with it best has been when they were physically active; my cousin with horse-back riding, my aunt with her job as an elementary school teacher (chasing down young kids, etc). My mom and I have milder level depression, and I can verify that when I felt best was when I was doing something, hence my saying TAKE A DAMNED WALK. Get the blood moving, get out in the sun, maybe make a small garden if you can, just get outside and MOVE. It helps, SO GO DO IT.
