Thanks for your replies, Sailor and Harker. I had heard of "Chemo Brain" but I associated it with "Memory Loss" e.g. peoples names, dates, etc.
Comparing notes with my support group, we all agreed, our memories had suffered from Chemo but discussion had not included "Decision making skills".
I found it frustrating to be capable before treatment and then so indecisive after.
Harker, it makes sense that this indecision could also be attributed to depression. I coped during treatment but floundered emotionally after treatment ceased. I had a number of stressful family matters to contend with during/after treatment but never before had I felt so incapable.
Thinking about it, I believe it was a combination of the chemo and the loss of security about ones health.
Sailor, your question about "feeling cold", I am of slight build and have always felt the cold, so I didn't notice a difference, I wish I could be more helpful. I was grateful when the radiotheraphy operators warmed their hands before treatment :)
Sailor, I enjoy reading your finishing quotes.
