Pregnancy after miscarriage

I had a non-viable pregnancy at the end of June; I found out in October that I was pregnant again and I have my first appointment around 9 weeks. Up until now I was managing the anxiety and stress pretty well, but this week reality hit. I am struggling and so worried that the same thing is going to happen to me again; I feel like crying all the time, and when my pregnancy symptoms aren't as bad as the day before I worry that I have lost this baby. I don't know how I'm going to make it to next week.
