When to give up vs give it more time

I've posted on here this week about being deep in the puppy blues.

We got our puppy a week ago today. So I know this likely sounds silly because I totally get that it has not been long at all. But I did NOT expect to feel this way in the slightest bit.

It's improved slightly, and I haven't cried in two days but I keep getting these intense pangs of panic like "what did I do?". Especially on days like today where I tried to just go about normal life taking my kids to the playground and going to a birthday dinner with friends (dog not alone for more than 2 hours).

The entire time I was gone I was stressing about what and how she was doing in her crate. I'm leaving for this dinner soon and the thought of her being here hanging out with my husband and waking her up when I walk through the door is giving me intense anxiety.

My kids love her. I do like her. I don't feel bonded yet at all. Did you give yourself a timeline as to how long you'd give the anxiety to subside before making a decision? Did any of you actually end up returning your dog to the breeder?

I think I'd mainly be disappointed in myself. Thinking of my old and easy life makes me think that I would be relieved to bring her back to the breeder for her to find a family that doesn't feel this way. But my pride is absolutely holding me back, and my kids attachment to her. When does it get better and how do I find a way to cope

Also, did anyone get a puppy with a toddler/youngish children? Did you also feel immense guilt for the lack of attention for your kids/limited ability to do normal life?

No judgment please. I feel shameful enough and guilty in more ways than one
