Scared to announce my pregnancy 25 weeks

I'm pregnant with my rainbow baby after a loss at 12 weeks in 2019. This has been a very anxiety stricken journey for me, I keep trying to look forward to each passing day but it's scary and I'm so scared of losing my pregnancy. My husband and I have told a few close friends and our family, but aside from that we haven't really put it out in the open.

I'm now 25 weeks and I want to announce it for Christmas, but I am terrified. All morning my mom has been talking about how she's going to post X, Y, and Z once I announce it, and I'm still just trying to muster up the strength to do it. I'm not ashamed of my pregnancy and I want to let the world know. It's a really scary time for me though and it's been really hard coping after a loss. I want to be excited but my brain constantly is in "anything can go wrong" mode.
