Hi I'm so sorry to hear of your loss. I've also been through something similar called a hydatitiform molar pregnancy, and the grief you feel is a physical pain in your heart. Not many hospitals provide support either however there are several charities in my area been creating memory boxes for families whom have lost a baby.
Don't forget your both grieving and both in pain, snapping and arguing with one another is just a way of letting this anger out, although it's the last thing you need. Unfortunately anger is just one of the stages of grief and let's not forget your hormones will be all over at this time so emotions will be running high.
May I suggest you perhaps look for an online forum to get some support from other mothers who have suffered and also ask your GP for counselling? I did neither and waited 19 years to actually acknowledge the mental distress it had caused me which was far too long, but back then there was no counselling and it was a very rare condition. I have a memory box and a little butterfly in my garden, not much I know but i see it everyday and it brings me comfort.
I now have two boys, but I can still remember that day as clear as anything and that was 22years ago. One thing I can remember someone saying to me back then was it mustn't of meant to be, omg I wanted to batter them! But now I think I wouldn't of had my boys if I'd had my other baby. I know my situation is slightly different to yours however the loss of a child is the worst thing ever to happen and I just wanted to share my experience.
Please get some support and I admire you for taking the first step and posting in here
