I feel that way and so does every photog and artist I know. One of the reasons some photogs (me for example) spend so much money on equipment is that we think (hope, pray) a different camera/lens/film/developer/scanner/printer/paper will help us make better photos.
Take some photos of friends, family, neighbors, patients and give them a couple prints. Think of photography as an opportunity for sharing views, experiences, and emotions, and that should get you through the doldrums that occasionally strike each person.
Like Chenick said, above: Shoot.
