Why not just mentor someone to take your place as an "office manager/director of operations/vice president" or something along those lines and pay him a fair salary for the work?
That way you get to keep the business but you also get to relax a little and unwind from being burnt out?
Business may even pick up a ton if you can bounce back mentally and sell full time instead of always dealing with field work...
