{{{Hugs}}}
You'll start to feel better when it's time, and not a minute before. It will happen, but it can't be rushed. You're in a natural part of the grieving process. If you try to rush it artificially, it <i>will</i> come back to haunt you later.
Do try to eat and take care of yourself. You do need to take it easy, since your body has been through a lot, but you need to nourish it so that you can heal physically. It will help your emotional healing as well. When we first found out that my pregnancy wasn't viable, I made DH take me home and told him I didn't ever want to eat. He told me he had to get something for himself, but he went out and got me a hamburger, fries, and a big iced tea (all the things I hadn't let myself have when I was pregnant), and I think it was the best meal I ever had.
