It's meant to show stress. Since I didn't have anyone on hand to pose and I despise self portraits (of myself) I just went for a picture of me squeezing a stress ball.
I used gimp to duplicate a layer and pick out the ball in colour. There wasn't that much contrast with the skin tone, plus I guess I was trying to make hand look more dismal with the black and white. Taken with flash in front of my favourite bed sheet (and on auto since it's hard to focus with one hand). I should really get a tripod.
