How can I solve my creative depression?

Do absolutely nothing for a while

Do new things, try new foods, etc etc

Create something. Find something in your day to day life that could be automated, see if it's feasible to automate it, and go for it.
Create a home server and you'll find reasons to write new stuff. :)
Even something simple like an app for your phone could get the juices flowing.
Find something simple that you do more than once and see if that task can be solved through code. Might take an arduino board and sensors, but the code is just waiting to written.

Do something else different (play games, watch a film or generally just relax and take your mind off it).

Drink beer and take a bubble bath.
