I'm retired now (thank GOD) but when I was working I experienced the same thing you're going through. There were times at work that I'd really get upset and sometimes depressed, but I always just kept telling myself that' there would be better days ahead,,,, and there always were. Like Ed said,, hang in there, try to dwell on positive things and get out there with those air guns and shoot some paper,,,, it'll take your mind off things.....
