Thank you ladies. I am definitely too much of a mother at times, or most of the time, if I'm honest. Nicolette, I am likely much as your mother unfortunately.

All my children get irritated with me at times. Zoe, I do appreciate your comment. I like to believe I am letting Evie grow, so perhaps my caring is not too overdone, as you say.
Unfortunately, we returned home from our trip early, due to Jacob getting into serious trouble. We are very disappointed in him, and uncertain what our further actions are to be, but they will be severe. We also returned to find Evie badly depressed. We knew she was getting down about things when we left, however she is quite worse now. The radiation therapy is starting to have its cummulative effect, in that she is more tired, and she has been experiencing nausea, vomiting and diarrhea, which we were hoping she didn't have to go through this time. However since they are radiating her abdomen, the doctor informed us that GI problems are inevitable.
She requires a great deal of rest, and will continue to become more tired as the treatments progress. I am certain feeling tired and ill much of the time does not improve her mood. Further, it is difficult to ascertain what part of her mood is the effects of the cancer treatment and what part is PTSD. However, Jim and I intend to not let the depression get any worse, regardless of its cause. We are pushing her, though trying to be gentle about it. We are insisting that she get up for meals, get dressed and spend some time with the family during the day, and some time outside as well. And Jim plans on continuing taking her for drives, daily if he can manage it. As a passenger naturally, as she is too ill to practice her driving right now.
An unhappy note as well, and no doubt also contributing to her depression, and to our worry... the results of Evie's bone marrow biopsy, received yesterday, were not good. She may need to begin chemotherapy once more as a result. Not certain yet however, more tests are required, but I will leave it at that until I have more details. In any event, we are not going to permit her to give up.
