Fuck depression its all about anger. Get your ass out to a shooting range. Take you a pic of the person you hate the most and spend about $100 in ammo shooting the motherfucker. If they won't let you do that there, find a field and grab a friend with a gun and proceed to US Army that target.

Then go to a gym and kick the living shit out of a punching bag. I dare you to stay on the bag for 2 minutes.
