Feeling sorry for myself

Yes, thats right. I am starting to feel a little sorry for myself. In the last 6 weeks I have fallen down the stairs, broke my tailbone, fractured my wrist, had my 4th c-section had a tubal ligation and had my gallbladder removed. I am taking care of 4 kids, one of which has Down syndrome and one of which is a newborn. I am tired and I am sore and I am tired of being sore. 3 of my kids are too big to be picked up. Everytime I try and breastfeed, the baby presses against my stomach and its sore. I can't take a deep breath. The house is a mess and laundry is piling up. My husband is crabby with me, I just feel like crying.
