Luckily, both of my girls took to their crates immediately. One is a puppymill rescue, so it really isn't too surprising she loves her crate.
I wonder if it would help if you put her in her crate for just 5 minutes at a time when you were NOT about to leave with a bully stick, so she wouldn't always associate the crate/door shut with you leaving her. Maybe you could just give her bully stick (or another "special" treat she holds in high regard) time at night with her crate door shut while you watch TV or something in the same room with her.
I'm sure you've already done this but make sure her crate is filled with a soft crate pad, blankets, a favorite plush toy, a shirt that smells like you...whatever her favorite things and comforts are. I have so many layers of blankets on top of the fleece beds in their crates I'll bet they feel like they are on clouds. I've often had people tell me they would like to cuddle up for a nap in there.
I'll bet eventually she starts hanging out in her crate if you keep the door open when she wants some quiet time.
ETA: I wonder if she would like an xpen better with her crate inside and the door open? I think this is a great option if you are pee pad training and don't want to give her free run while you are out.
