Hi, my name is Anne and it has been awhile since I've been on the board but I am a cancer survior.
The best thing you can do for your Mom right now is talk to the doctor and get his guidance. Not everyone experiences depression, nor at the same point in time or to the same degree. I, for one, did not really experience any depression until I had been back at work for about eight to twelve months. I tried to deny it for a long time which only made matters worse. Finally I sought help about a year ago.
As it has been explained to me, being diagnosed with cancer or being the care-giver one can go through a range of emotions, denial, anger, depresssion and finally acceptance.
This September will be the third anniversary of my cancer operation and I'm happy to say, I have finally accepted.
Please let us know how your Mom makes out with her Doctor.
Take care and hang in there.
