Hi Mel,
In my own experience cancer treatment was scary for all of us in the family. Stress anxiety fatigue change in roles all added up to a hard time. I felt I was losing the relationship we had, even afraid he couldn't put up with me any more. For years we hadn't voiced our feelings and fears to each other. Soon after chemo, I was offered sessions with a qualified counsillor at the local public hospital for my own sanity. The main lesson I learnt from that was; feelings are not necessarily reality, feelings of anxiety do not equal who I really am.
