Advice for not being afraid?

Lynnie • Pregnant with our rainbow 💜🌈
I keep reminding myself that being worried or afraid will have zero impact on the outcome of our next pregnancy. But at the same time, I feel like part of me is almost dreading becoming pregnant again. I really want to be pregnant, but like I said I'm just still so heartbroken.
For context, I had a missed miscarriage at 8 weeks that ended in D&C on Jan 25. Today is the first day of my first period after all of it. So I find myself kind of having to confront whether or not I'm actually "ready" to try again. 
I feel like I'm probably as ready as I'll ever be. But how did you ladies keep your worry in check? How did you get yourself to enjoy the TTC process again? And how did you learn to celebrate the new pregnancy without being overwhelmed by the fear of another loss?
