I am sorry this is happening. I wish I had some great words of advice or wisdom for you. It must be so hard with all you have on your plate: 3 kids, a newborn, postpartum hormones, grad school, and the constant stress of H, is more than anyone could handle. I think even if you feel you can do it all, there might be a compromise some where, and I would rather that be your choice, not a consequence of the circumstances. As you know being a nurse, stress and all that comes with it is very dangerous for your health. I fear you are under tremendous stress (including lack of sleep).
I like how 25 put it: what advice would your past self tell your present day self? It is very hard to make decisions when you are in the thick of it; you are in pain, spinning, and it may be too much to make sense of anything. Think about yourself at a time when you felt strong and confident. What would she say to do? Hang in there. Rely on the safe and loving people right now as much as you can.
