Hi, congratulations on your new bunny addition!
What you have described is completely normal, she has gone through a lot of changes in a very short space of time so is likely to be nervous! I remember when I first got Oscar nearly 2 years ago, he spent the first week nearly hiding in the corner of his cage.
You will need to give her time to settle, then try just sitting next to the cage reading to her maybe? so she get's used to you and your voice.
When she is comfortable in your presence, try to get her to take food out of your hand. Some tasty treats are good for this- we had some dried apple pieces with Oscar which he loved! It takes time, but soon she should hopefully take food out/off your hand.
When she is comfortable with this, try stroking her when you feed her. Then you could try to get her to jump onto you when you feed her. It's slow progress, but it's all about building up trust. Rabbits are after all a prey species, being picked up usually means they are about to get eaten!
You may find you never have a cuddly rabbit, Oscar and Jessie love a bit of fuss when they are on the ground, but don't really like being picked up. Oscar just about tolerates it, but I know he doesn't like it very much. It's been a long time to even get to this point though!
Good luck (pictures are needed too!)
