I really don't have much personal experience to draw on here, but just to add my two cents, you might try to think about why you initially became an entrepreneur, techie, developer. Something that always makes me feel better no matter what my work-load or responsibilities is spending some time on a project just for the sake of my own interest. These are NOT money-makers, just rough ideas for anything that truly interests me from a tech standpoint. Like maxdemarzi said, do something to regain confidence, interest in your work, etc. You can't fix all these problems at once.
