Here's my advice. You don't have to have a new gig lined up immediately after you leave your current one. Take a little bit of time off. You probably need a little relaxation and little time to think and be creative again. I promise you new ideas will come in due time. If people are looking for a developer, and you have developer skills, they are going to hit you from that point and ignore the rest. In due time you will gain that same passion you had before but for a new idea and you'll be right back where you were only with a bunch more experience than you had before so things can only get better.
