So sorry for your loss.
How is Jitterbug doing? Is she eating and pooping OK?
Is there a reason why you do not want to re-bond her? Since she was bonded before, she will be much happier if you re-bond her…
In the meantime, you can try giving her a “stuffy” to snuggle with. It helps to rub her scent all over it first, and then make it “groom” her and snuggle with her. Just be sure to only let her have access to it when supervised, to make sure she doesn’t chew it and eat any of it. There are some on this site, and some people recommend looking for rabbit dog toys or baby toys, as they are safer.
As BunNoob says, also try to spend as much time as possible with her. Lay on the floor near her, talk to her, etc.
