Your situation sounds very familiar. I was once a startup CTO to a vc-backed company with very successful founders. Although I was a major shareholder, it was pretty clear that everyone was replaceable at any given time. In the end I resigned simply because the work environment was not compatible. It was affecting my health and being a "free electron" didn't earn any points (except during fundraising rounds). My suggestion is to take a break and reflect on your experience so far. Try to pinpoint the type of people you want to work with, what your personal boundaries are and what environmental elements can make you happy. Keep in mind, value exchange will define your position.
