From the outside, you could say with a good bit of justification that I needed to go learn how to ski or drink some beer or something. I'd argue though that "getting lost" is one of the rewards of working on a startup project. There's a mix of satisfaction in the sacrifice, the joy of unbridled creation and the camaraderie of taking on something that you may or may not pull off with a lot of people you respect and trust.
These days, I live in a nice part suburbia with my wife, who would feed me every 10 or so hours during those projects. She's getting an MBA and I'm running the business I started, but our pace of life is much more normal.
My advice, having lived on both sides of the fence, and without knowing the specifics of your situation past what you posted, is to grab as hard as you can for that vision you see. You'll learn, grow and stumble into things and people that will greatly enrich your life.
Good luck!
