You're number one priority should be to solve the drama and clear it out of your head. You can do whatever you want, but with the drama in your head, it ain't gonna do much.
Doing fun high-adrenaline stuff helps to imrove my mood. I have a season pass for SixFlaggs and when I feel down I go there to ride rollercoasters all day long. Really makes you feel great.
Motorccyles rides are also great.
However, nothing beats a real good conversation about the drama with a good friend (preferable a girl) and some huggs!! A big hugg from one of my friends always does the trick. Pitty she isn't always around!
I guess it has nothing to do with workouts, but from what I read in your post I assumed you are not likin 'm due to mental issues. Whenever I feel blue I don't feel like workin out myself and whenever I feel happy, sporting is the first thing that comes into my mind.
