The last company I worked for acquired 2-3 companies per year, And it became obvious that in some cases the people who part of the acquisition were burned out and wanted to be free of their responsibilities. But they didn't have the financial wherewithal to just quit and move on. A lot of them shifted into roles with different but less critical responsibilities. One person basically just turned into an evangelist, meeting customers and painting visions. It wasn't easy for them to keep going, but it's easier to keep going in that type of position because they weren't responsible for keeping the lights on. I realize this isn't an answer, but maybe this is a way to keep going if you decide to stay with whomever acquires your company. >The product is just too complicated (tons of domain knowledge required) for someone to come in and take over. This is a very heavy burden. I was here once as an individual contributor and I ended up in the same state you are in now. It was absolutely awful. Even if somebody can't take over 100%, can they take over 25%? Also, as others have said, find somebody to talk to. Assuming you have a decent marriage, cry in front of your wife so she knows what's going on. It's hard to move when you feel the whole world is resting on your shoulders.
