Based on the first half of your second paragraph, you might be happier working for someone with an interesting product who's willing and able to take on the doubt and fear. It might get you from here to "better" faster. Or at all. I think starting your own thing will also make you forget you have a life. But are you honestly able to power through the doubts you raise, to a meaningful next state? If you can afford it, you might do the two columns on a piece of paper exercise, quit the job that loses, then exhale a bit, think, and explore.
