You probably heard this before but it works! Get out and walk in the sunshine. Walk around your yard, sit in the sun for awhile. Find an ant and follow it! Just get outside and stay outside for a few hours. Pull some weeds, water the weeds, wash the car, the sidewalk, the driveway. Sit down in the grass and look for a 4 leaf clover or lay down and look at the sky. When I get the drags I make myself get outside and do something even if it is just sitting on the stoop watching and thinking.
