Breaking down

Kimberly • Married to the love of my life for almost 5 years. Mommy to 2 super heroes. Recovering from the loss of my 3rd baby.
I found out that my baby didn't have a heartbeat at 12 weeks. I had a D&C this last Monday and my in-laws came to help take care of my kids for the week. 
Today is the first day that my house hasn't been full of people since I found out and I feel like I'm just breaking down. I feel mentally and physically exhausted and so deeply sad. I'm having the hardest tie finding the will power to get up and do anything. I really just want to curl up in a ball and stay there forever. 
Any words of advice or encouragement would be appreciated.
