Susan - you it the nail on the head! You are not nuts! Anytime a change occurs, it can be so stressful even if it's a good change that happens. There were times when I felt resentful, too, because of all the change that occurred in my son's cancer, mentally, physically, financially to me as well as to my son. On top of that I felt guilty for even stressing over my own changes when he was going through so much himself! However, for me, four years later, I can say that it does get ever so much better - I can enjoy the "now" so much more and the stresses I had previously have become "small stuff". Surely, your sister's vacation will be beneficial to her, and to you, too! Let us know how the vacation went.
