These are 'first world' problems. It is all about perspective.
You have a roof over your head, your family are healthy, you can eat. It sounds you bit off more than you could chew with the house.
Worrying is normal, but being miserable over it is is just plain needless melodrama caused by your hormones - so get a grip.
Just prioritise the essential and if it means a bit more debt well just do it - it is better than being uncomfortable/miserable.
I can live with an ugly bedroom, but I can't live without a working kitchen. Forget the dishwasher, you CAN live without one. That is NOT a priority - but an oven?
You need a clean place to cook - so focus on the kitchen. Get a loan if you need to.
When you say your bedroom is falling apart - is that an exaggeration? Is the ceiling/floor/wall coming apart? Or can you live with shoddy cupboards for some more time?
It is only January. That is enough time to get a kitchen done by March. When it is time to do the cupboards in the bedroom, just camp in the lounge a couple of days - having a baby won't make much difference.
If none of this can happen - then get a grip, and just make do, be brave and don't make a fuss. Count your blessings.
