Good luck OP. Sounds like a good plan to give it 100% for a couple of weeks and then see where things are at.
Listen - there's no shame in helping her find a new home if you do decide to. If you can place her with someone you know (I think you said earlier that you could), then that's even better.
In the meantime, in addition to what others have advised, I just wanted to suggest a couple of things. Forgive me if you've already addressed these and I've missed it!
Does pup have a play pen? Could you set one up in the kitchen and pop her in it with toys while you cook? Or otherwise, could you have toddler in the kitchen with you, and put puppy in a playpen in the other room? I say playpen because this would give her more room to play and entertain herself than a crate. Maybe you're already doing this?
Also, does pup have any kind of routine? If not, it could be a great time to give her one, over these next two weeks! Generally, you want to do something like: 1 hour in pen/crate > out to pee + play with you > bit of training > back in pen/crate for 1 hour. Basically, 1 hour rest, then an interactive break. Rinse and repeat.
If you do this, you'll find that she starts settling at certain times of the day automatically.
Also, just to add that I 100% feel you on the overstimulated biting attacks. My dog did this as a puppy/teenager, and it was horrible. The more frustrated/loud/physical I got, the more hyped/loopy/bitey he would get. I had to learn to calmly say "ok, time out", pop him in his pen, and leave him to chill his tits (and also chill mine).
I hope this helps, and good on you for giving it a shot. You've been dealing with a lot.
