Take heart! We all have gone through this phase, and you have already stumbled on a solution: having an alternative creative pursuit, such as writing, will help. I used to tell my students to develop at least two creative skills, so that at times of necessity one can switch, and eventually switch again as needed. The possibilities are infinite. Each reinforces the other. There is also the choice of new ways of photographing, new perspectives. Much more to do with refreshing the brain than refreshing equipment.
