Here's a few suggestions just based on what I do that works.
First of all, have a crate schedule and stick to it. Dogs have internal clocks like we do. Puppies thrive on schedules. They know what to expect and they get less anxious when they understand what's expected.
For example, my pup is in the crate obviously overnight, but she spends another 4 hours from about 830-1230 before my girlfriend gets home to let her out. Even on the weekends, she spends that time in the crate and I usually chose that time to get errands done.
Also, a few things that helped my pup adjust when she left her litter was to put her in the crate, and then lay down next to the crate but ignore her. I would usually read a book or jump on my Ipad. When she fell asleep or at least got uninterested enough, I would walk away. I also played some music and HD Youtube videos of dogs playing on a beach for the first 3 days. My pup was littered outside in a city so I wanted her to have some sort of noise overnight. Seemed to have worked.
If my dog gets extra whiney or barks in her crate, I put a sheet over it. I actually always have a sheet over it, but I'll pull it down completely when she cries or barks. I dunno what it is, but they hate barking in close quarters like that. This has worked on every single one of my dogs.
As far as separating her. don't respond to her cries and bad behavior. They seek any attention, even if its negative attention. And then be heavy on rewards when you come to her and she's calm. Demand she sit before you engage her.
Work on your crate training. Everything should fall in place.
And pups are pups. My dog is very obedient and very calm, but still has her moments where she seemingly flips out when she's not near me. Like taking out the garbage, everynow and then I hear her crying her eyes out from outside.
