Can someone talk me off a ledge? The nursery isn't done and I'm sobbing at 4am

I'm 37 weeks pregnant and have bought everything myself for baby/the nursery, assembled all the furniture, decorated the room as best I can. I've been obsessively nesting and cleaning the house for the past month. I feel like I've been doing everything I can on my own to get ready for baby girl.

My husband's two jobs for baby were to get blinds put in the nursery (there is nothing there now, so just 2 large windows) and hire someone to plaster and paint (it's a 100+ year old house and there are literally holes in the wall that need to replastered, and old wallpaper hanging off the walls. Baby is now nearly full-term and neither of those jobs have been done.

The past two weeks we've been hit with majorly stressful financial setbacks. The first is house related that is costing us tens of thousands of dollars and must be sorted asap legally, and then yesterday a piece of our car's engine exploded and the car is a complete write off. So now we have to look at how we can afford a used car on top of everything else.

All my mind can think about it is how I've let this poor baby down. How is she going to nap with no shutters in her room? It's not fair to give her a nursery with holes in the wall and bits of the wall coming off. I can't stop crying. I want her to have a fair start to life and feel like I've let her down already and she's not even born yet. Can anyone please rationalise with me and tell me it's going to be okay? All this stress is tearing me apart.
