It's been 6 days since I found out

That I am having a missed miscarriage. The earliest I could schedule d&c was this Monday. I know that I haven't been able to start moving on because I am still pregnant. I'm so terrified. I'm so angry. I hate the fact that I didn't want to get pregnant but when I did I got my hopes up and got excited and my partner was so excited and now I hate every single waking moment and I can't eat or sleep more than a few hours at a time. I still am peeing constantly and having headaches and sore breasts and I'm so fricking mad and sad and overwhelmed and I just don't want to be reminded that my body is pregnant with nothing. This is the worst feeling. I have never in my life felt so shitty
