Sorry to hear about your depression, MRBUBBLES.
Accepting failure is part of any truly original pursuit. You now see how inert the rest of the world is, how irrational people are in clinging to old beliefs, and how non-responsive they are to new ideas.
Look at your entrepreneurial attempts as an exciting journey, where you are learning and increasing your awareness of reality at every turn. This journey IS the reward.
It doesn't matter if no one is interested. Are YOU interested in your path?
