Scared to set up nursery?

I've been struggling a lot lately. We have beautiful things for our baby and everything we could possibly need but currently it's all still wrapped in packaging or has the tags on it and it's sitting in the middle of our newly painted and carpeted nursery. Every time I try to organize I am overcome by paranoia that she'll never get to use any of this stuff 😭.

I have no reason to think this as this whole pregnancy has been completely normal and healthy and I go to all my appointments and the doctors say everything looks great. But sometimes I get so upset thinking "why do we deserve a healthy beautiful baby" and I get overcome by anxiety that we'll be that rare statistic that doesn't get to bring home their baby.

Please help I need advice from mothers who have experienced this kind of paranoia! I also worry about worrying so much because I worry that all the stress is bad for our baby girl.

Any advice is welcome
