It sounds to me like you're stuck because you don't think you have the drive to try another startup but believe that there isn't any interesting corporate work.

It sounds to me like you're stuck because you don't think you have the drive to try another startup but believe that there isn't any interesting corporate work. Both of those beliefs may be wrong: - you should be able to find work in the healthcare sector and use your experience to really improve things or join a startup that is past the grueling early stage - you might be able to find a different environment or a different partner for another try at a startup. Taking on a day job for a while might expose you to other people with energy to start up a new venture
