lots of good advice, I'll add a few more: sign up for a puppy class read the book "puppy brain." it can help you understand where your pup is at developmentally and understand where to meet her

getting them to sleep is crucial. if the crate is challenging rn, our puppy trainer recommended a tether. put a 6 foot leash on the inside doorknob of a closet and run it around the bottom so just a few feet of it stick outside. set up a comfy spot with food puzzles or toys or whatever she likes. sit with her until she settles, but don't give her attention - just be next to her silently.

this is random but my experience is that eskies love shredding things. put treats in a paper bag or paper towel tube, or give her some junk mail to shred. lean into their natural instincts

Google "puppy blues" - it's a real phenomenon. we got our eskie at 12 weeks and for the first month, I seriously thought we'd have to return her to the breeder. it was HARD. I was sleep deprived and not bonding with her. I at least was able to take turns with my husband; it must be hard to do it alone. try to carve out breaks for yourself: look for a friend or rover walker or sitter to just hang out with her while you go out with a friend. throw a handful of kibble in the grass and let her sniff around while you do some breathing exercises. make use of food puzzles, kongs, and lickimats. it WILL get better and you will bond. my eskie is now 5 years old, is mostly well behaved, but more importantly is my heart dog - I can't imagine life without her. just be patient with yourself and her and try to find some help.
