Hi Penny,
Yes, it is one hell of a shock to have a BC diagnosis, and the treatments go on for some time. I am down the track, but I still recall the emotional journey as well as the physical one.
It does change you maybe; you get your priorities sorted out, start to enjoy the simple things in life so much more, plus maybe take life day by day.
Good luck with everything. My advice is take it slowly as you can; the treatments can have an accumulating effect and I have found I go in a slower gear now. Listen to your body, etc. TC ..Kathy.
