If the business is to survive (and continue to support you & your employees), you have something like these two options:
1) You continue at the existing intolerable grind until you lose it. The entire mass of work that you're currently doing will suddenly be thrown to everyone else, along with whatever else is required to clean up after your personal implosion (will they even know where you are or if you're coming back? will you start throwing servers out the window or screaming at customers?). Somehow with incredible difficulty they may figure it out and rescue the business, in spite of you.
2) You grind up this bitter pill and start giving it now, in little tiny doses. Hand out chunks of responsibility to others, and answer questions but don't micromanage; let them make their own mistakes (and clean them up themselves) until they've got it under control; shuffle things around as needed until folks are comfortable; repeat. Either you will make your way to a business that is sustainable, or you will find that this cannot be, in fact, a workable business that doesn't ride entirely on your back. Which means you should try something else.
It think it should be obvious which path is easier on your colleagues/employees.
If this were me, I think I'd just say "we're going to start having "X got hit by a bus" drills, and you guys have to handle something completely without me". It won't be as good as if you did it yourself, probably, but there's no way in hell they'll get any better without practice.
