I mutter a lot of unprintable things under my breath. I complain to my wife. Sometimes I rage on Facebook. I get mood swings.
Exercise doesn't do much of that "endorphin rush" for me. I do enjoy shooting, but buying a lot of ammo gets between my wife and I, so that's a hit and miss hobby. I'd love to just take more time OFF from work, but that's not happening.
Mainly I think I'm just in the wrong position - I don't enjoy the job I currently am assigned to. Hopefully when/if I get the residency I want, it'll change. If not, I may just become a paramedic, make 1/3 the salary, and hopefully be 3x happier.
