I just feel like I'm going to break

I just need a place to vent. I need a safe space to scream to cry and then figure out what I'm doing. I had my third baby three weeks ago there was some complications and he was born three weeks early. My husband had to go back to work immediately. Leaving me with a newborn and two toddlers when I could barely stand or move from my pain from the complications of birth. Now my uterus I believe is falling out and I can't get into an obgyn as they are booked out in my area. I can barely move I'm so uncomfortable. This morning my refrigerator caught on fire. We lost all our food fridge and my breast milk to the fire. Today just broke me. I'm trying to keep it all together and I can't. We have no money to replace the fridge or the food. I don't have enough milk now to feed my baby for a planned surgery I'm having in two weeks. I am sleep deprived in pain and just feel like I can't take care of my kids. My family who was supposed to help me after the birth all got COVID so I have felt so exhausted alone and now I'm not sure how I'm paying for a fridge or feeding our family much less how I'm supposed to make up for my lost milk and I'm terrified my uterus is going to fall out. Life shouldn't be this complicated and hard. I just want to enjoy my new baby and I'm under so much stress.
