I want to try again but I'm so scared of another m/c that its taking over my life?

I had a miscarriage a few weeks ago and my midwife cleared me to try again in a month or so. And I have decided I want to try again, and nothing would make me happier. But since my appointment with her Wednesday I haven't slept at all, I'm so terrified of losing another baby. She wants me to get a progesterone shot as soon as I get a bfp, which is great but I'm still so scared that I will have another miscarriage. I'm not worried about getting pregnant (even though this took 8 months this time) I'm just dreading the worried part. I'm not going to want to tell family members, or even my friends just because I can't handle the calls again to tell them I lost it. So my question is how did you cope with these worries and how was your next pregnancy?
