Puppy Blues or give up puppy

My husband and I have been planning to get a puppy for months now, we’ve checked out adoption events and shelters with our 6 year old son. When I browsed a puppy adoption event I fell in love with a 9 week old Labrador Retriever and eventually decided to adopt him. He went home with us and I didn’t understand why I felt like my world was spiraling down.

The first night I did not get a wink of sleep, it was a mix of anxiousness and also the puppy crying. I had all of the puppy care materials because we kept some of the puppy items of our Morkie mix, he’s 3 years old now.

I slept nearby the crate and he slept soundly the first 2 hours then he woke up every hour. I gave him 2 potty breaks that night but still cried. I made the regular “shhhh” sounds to train him early he did quiet down for an hour but woke up crying again at 4am. Daytime he was okay, he slept most of the time and played in the afternoon with my son. The night came and he had his last feeding at 8pm and slept around 9pm, the puppy fought and cried for 15 mins. He woke up 3 hours after and cried out for about 30 mins (I checked him and consoled him whenever he stopped crying also he peed on the pee pad in the playpen and I changed the pee pad so he wouldn’t smell). The puppy slept and woke up at 4am but this time he cried for an hour and I felt so helpless at this point my heart was sinking already, like I kept saying to myself that this is hard and I can’t imagine being like this for days or weeks. I cried so much because I wanted this but how come I’m regretting it now.

I work from home fulltime but I have a very somehow demanding schedule (meetings and sudden slack calls) so I don’t if I can fully commit to this. My husband also works but he is in the office, but right now he is out of town with his mom so it’s all me for the kid, the Morkie and the puppy. It is now crossing my mind to return the pup to the center because they did say that sometimes adoptions don’t workout, we have to be both fit for each other. I feel like trash because of what I am thinking but my husband said to give it 1 more week or when he gets back from his family trip. I don’t know if I can keep up because I am already mentally breaking down, rounding up my responsibilities. I feel super guilty because the puppy is perfect and I know for sure he will be loved more with someone else but at the same time I want to keep on trying too. What am I gonna do :(
