It's so raw and new right now. Cry as much as you need to. It's an important part of the process.
You will heal eventually. Everyone's a bit different, and some feel their loss longer than others, but either way, you will heal. I found out that my pregnancy wasn't viable before Christmas, and I am in a much better place now than I was then. Not to say that I don't care, I do, and I do sometimes feel sad about it still, but I am on the other side of my miscarriage, finally. You will get here too.
In the meantime, love and strength to you.
