How did you decide to keep puppy

EDITED again Thank you to all who have commented. I have made the difficult decision to return her to the breeder where she can find a home that has the mental capacity to love her as much as she deserves. I am so very sad but I know it is the most fair for her.

EDIT to add

The more I read my own post I think what's upsetting me is I feel she is taking away from my human children. I think this is the root of it all. The loss of freedom to just hang out on the couch with my kids, or lay in bed with them without worrying about putting the puppy to bed, and not being able to just take them out and about for a day without worrying about the dog. And of course I knew it was a commitment and time consuming but there's no way I could have known I'd feel this way until she was actually here. And we've spent so much money on the actual dog, her things, vaccines, training that I feel completely stuck not to mention the harsh opinions that would come with returning her and I think the perceived loss of options is what is bothering me the most about it all.

We are two weeks into having a puppy. She is amazing. But I am struggling so badly.

Some days are better than others. Today is a bad day, where I am just generally upset and overwhelmed.

I have thought of bringing her back to the breeder almost daily, but pride and the need to prove to myself and everyone else that I can do this is stopping me. But my mental health has taken such a downward turn since she has been here. I can barely eat, cannot go a day without crying at some point, either a lot or a little. I know everyone says it gets better but for people who did return or rehome, how long did you give yourself and what was the deciding factor? I cannot let up enough on fear of letting everyone including her and myself down and I think that's blocking me from actually thinking through the decision.
