I completely understand your feelings. Your mother seems to be faring well which is excellent. If she is feeling well and her spirits are good, I'd suggest you help keep that up. A good positive attitude goes along way and she needs that to fight this terrible disease! Knowing how insidious it is, I recommend you keep an eye on her and her progress, physical health and various symptoms to see if she has a relapse. I've seen many posts on this site where people have been in remission for years so don't lose hope!!
