My heart goes out to you. It's never easy to lose a bunny friend and I think it's all the harder when you know how hard they fought to stay with you, and how much they have been through.
The first gift you gave was a wonderful chance at life for a bunny that deserved a break, and the last gift was one of a peaceful and dignified departure. To be commended.
Big hugs, I know how hard it is, when you've nursed a bun, as so do many others on RU. We feel your pain.
