We can save you from yourself.
Look at http://www.nasa.gov/images/content/690958main_p1237a1.jpg -- every dot in that image is a galaxy. Each galaxy has over 100 billion stars. Do whatever the heck you want in this world. It'll work out.
I can also agree to this. I was more or less in the same boat (possibly a bit worse at times). I had my idea for a startup and decided to use it as an objective to get me moving forward again. The first step for me was going to London and checking out the startup scene there (Techhub). It in a way, it gave me a boost and energy to flesh out my ideas and plans.
Sometimes, a change of atmosphere helps give you the initial push that one needs to move forward.
I visited SF, Chicago, NYC and Austin, TX all in the last year - each trip has made me more and more inspired.
