Honestly, I should probably just apply to some places and see if I can get a better job, but for some reason I am afraid I will just get turned down.

Consider it rejection therapy, then. It turns out it's OK to be turned down; and you might at least learn something about the interview experience.

Some thoughts:

• Try working for a larger organization where there are more diverse internal opportunities.
• Try working for a much smaller organization (i.e. a startup or small nonprofit) where you are compelled to work on different aspects of the project.
• Try programming-as-sport: programming competitions such as Ludum Dare.
• Try a different technical hobby — learn digital electronics, for instance.
• Find an open-source project that you already have an incentive to work on. Do you use an open-source text editor or other tools? Are there features you'd like those tools to have?
