Are you getting any professional support (eg counselling) from anyone? Perhaps that could help more in the long run than sedatives. I struggled with a lot of depression for weeks after our mm/c and that was without losing a part of my own body. As much as it hurts, you need to work through the grief rather than hide from it. I can tell, even from here, that you're having a very hard time and I'd really encourage you to talk to someone, if you're not already doing so. I wish I could do more to help.
