The goal is to make them think the crate is a happy place, so if they're mainly crated when you leave, they'll associate it with something negative (isolation). It's a good idea to feed in the crate, special treats in the crate, also crate when you are nearby so that it doesn't always mean isolation (you're doing this already by sleeping near the crate), there are all kinds of "crate games" you can play too. A fun one is to put a really really high value treat in their crate, with the door closed (they're outside of the crate). Let them try to figure out how to get IN.. wishing they were in there. Then open the door and let them have the special treat inside. I'm working on this with my fella too... who has separation anxiety.
Also, never ever ever use a crate for punishments or time outs.
I do think some dogs will never take to a crate, but also a lot can be accomplished with actual crate training, versus just putting them in a crate when we need to leave the house.
If she's food motivated, try something like a kong, so that it takes longer for her to eat, and she's associating that nice experience with her crate. You start with just kibble that comes out of the kong fairly easily, then make it more interesting for them by freezing it with some peanut butter, etc.
My guy is 14 weeks now (approx, he's a rescue) and he still does not like his crate either, but it's getting better. He can now go through the night without fussing and no accidents, but that has just been in the last week or so. I would give a little water at night if they seem really thirsty but definitely not too much.
In the rescue, we always tell people to crate a puppy beside you if you can... I think the logic is that sleeping with the pack is quite significant to most puppies, so it's particularly hard on many of them to be alone at that time.
If you work from home or are home during the day, I would definitely be working her up to being alone in her crate... starting with shorter periods, then longer and longer with lots of rewards. It's hard when you work 9-5
