It sounds to me as if you need gift yourself some mental time off. You're clearly an entrepreneur, so I'd caution against getting a job, but you've not had a follow up hit and may have lost a little confidence in yourself and can't see the joy in trying to build something new.

You're in a fortunate position financially so I suggest you use that freedom to detach and replenish. Ask yourself, if I allow myself to do absolutely anything (or nothing) for the next 6 months what would it be? That's a pretty exciting thought right? Not only will you break the cycle of intellectualizing your situation, the process of self-permission will open up new ways of getting out of these ruts in the future.

If it were me, I'd switch off every device and read the Guardian's 100 best novels of all time.
