Feeling totally disorganised and panicking 😢

Natalie
I'm going into panic mode now and I can't stop worrying !!
I'm due 2nd December but have a low lying placenta so if its not moved I will be having a c section at 38 weeks and right now feel so unorganised and like we'll never get everything organised. 
We have just decorated and bought new furniture and bed for our little girl as she has moved into the bigger bedroom in our house so the baby can have the smaller room and we luckily kept most of the big things like the cot and Moses basket and nursery decorations etc so we only need to buy the furniture for that room but I don't feel like we have hardly any clothes and any of the practical things like nappies etc not to mention I've not even thought about getting any of the things I'm going to need. We still need to buy the bottle prep machine, streriliser, bottles, pram and all the clothes she's going to need.
Every time I'm shopping I pick little things up clothing wise etc and we're going to get the bottles n steriliser next month but I've no idea when we'll be getting the pram and not to mention Christmas that's just round the corner we have all that to get as well !!!
It's all getting to much and I find myself lying in bed worrying about it at night and I can't seem to stop the worrying ....
Please tell me others feel the same and arent as organised as I see some people are. When I was pregnant with my little girl 5 years ago we didn't even have the nursery done by the time she arrived n that didn't seem to worry me 😖
