I think it's more because you're a minority. Investment projects like this work because of the number of people investing at once. All invest a little and little is lost if it fails.
Kickstarter projects are cool and people love the idea of investing in something where they actually get to own a shiny gadget if it succeeds. Most startups are not and the thing that people own can take a long-long time to reap any value.
You're not unique in this and basically have two choices: continue what you're doing, push through it, and see it as your adult responsibility. Ultimately many jobs are like that, you don't love them, but they bring home the pay-check. The second option would be to do a search for what you really want to do. One great book with tons of bios of people who have and turned out happier for it is: "what should I do with my life?" In the end, you'll probably settle for a combination of both. Lastly, it may be that you over-pushed yourself and burned out. That can lead to similar negative feelings about what you are doing now. It may be a good idea to approach a medical professional and discuss symptoms and solutions.
