How do you cope with a miscarriage?

I had a miscarriage of mono mono twin baby girls who had trisomy 14. My d&c; was almost a month ago and I cry everyday. I cry every night. Last night I was up standing next to an empty crib clinging to a blanket and a stuffed animal for my babies. I found a dog that I want to adopt but my parents say I can't bring it into the house even though I'm moving out in a month. They just think I want a dog. They don't know the real reason I want a dog and I plan on registering her as a therapy dog because the mc is about to drive me freaking crazy. No one knows how much i cry. No one sees me slumped over their crib at 3 am crying because all I can think about is them. They think I'm normal. I'm not and I need help but I can't afford real therapy.
