Hemi, our youngest rabbit

We have some sad news. One of our youngest rabbits, Hemi, is probably paralyzed from the hips down. We noticed she was having difficulties walking while she was playing in the garden. We took her to the vet but since she was very scarred and the floor over there was to slippery he couldn't make a fair diagnose. He told us to let her be by herself for some time and than wait and see if it'll just pass. This morning we tried to put her back with the others in the garden, but we noticed it just got worse. When we picked her up we saw her paws where just hanging there, not trying to scratch us - she always does that, so we immediately knew something was awfully wrong. We tried to move her legs, but felt there was not much life in her right leg. Her left leg still has some muscle but not enough for a healthy rabbit. We've had rabbits ever since we can remember, so we get the hang of it... Now we're in doubt of what to do... She lives perfectly with it, but doesn't it endanger her overall health? Our vet's on vacation right now, so we have to wait at least a few more days... He assured us last week that apart from her legs she looks very healthy, has a good, strong back muscle and clean teeth and eyes. Doubt! :(
