New puppy

I’m currently 18 weeks.. about 2 weeks ago hubby bought a puppy. I’m depressed because this puppy requires more work then a newborn. I cant take it. She barks through out the whole night. Poops everywhere except her puppy pads or outside. I have to get up every 5 mins to clean up her pee and poop. I should be resting instead of getting up and tending to an animal i didn’t agree on. She’s sweet and loves me but she’s one of those breeds that are hard to train because they’re stubborn. Help!!
