I feel your pain. I honestly think you should talk to your wife or your close friends about this. You'll be surprised how people help out when they know you are in distress. Also, taking on a different activity that involves leadership might greatly help in boosting your morale. What you have done with your company is quite commendable that you should be proud of. If I were you, I would focus all my energies on the company's future post acquisition. To think of ways of growing the company beyond what it is today and see the acquisition as a possible out in that direction, not the end goal in itself might be helpful. You might also want to try to accomplish something in a field that you have no clue about but is not super hard on your brain. For instance, you could learn ballroom or Tango. You could also join a basic mountaineering course. You'll be out in the nature and accomplishing an endurance task. All your energies will be focused away from your day to day mind numbing activities and towards accomplishing a very different goal. Good luck !
