I think taking your rabbit along is a good idea. Everyone needs comfort and it can be your symbol of support.
Try not to think about your Al-non experience as the basis for this new experience. That was a while ago and a different Rose ago too. You are stronger and more determined now. Circumstances are quite different too. And you have a lot of support. I, for one, will be cheering you on!
Sleep well, Rose. You sound so tired. I hope your rest is a deep and peaceful one.
