I really really hate to say this, Shelley, but she's probably broken her back. We raise, breed, and show so I've had to deal with this before. rabbits have very fragile bones, which is why we're taught how to pick them up so they don't freak out when we do so. They can and do break their own backs, in their cages. It's hard to say for sure what happened that made her do so, but I think that's the problem.
If that is the case, the only thing you can do is put her down. I've lost some of my very best show rabbits, and it's hard.
Try picking her up. Bring her inside, set her on a couch or carpet. If she's dragging her legs, it's not good. There's no way to fix it once this happens.
I'm so sorry this happened to you! I've become accustomed to it, so I give them the best life I can while they're in good health. We have over 30 rabbits, and they all get special treatment from my kids and myself.
Please let me know how things are going. I know it's hard to put a pet down, so I'm here if you need me
