The experience that Sue is going through pushes your faith in everything to its absolute limits.The only thing you know you can trust is yourself,and the knowledge that it will inevitably end.I think in some ways it takes you to a point that when that end comes,you are actually relieved its over,but the anger at the unfairness of the nature of that end takes much longer to leave.
It is the experience Sue is going through and the one i went through,that highlights the reason why just about every one on theses boards who has a partner,uses the phrase "we" when talking about treatment.It truly is a disease whose effects torture the mind of the sufferer and the carer equally in different ways.

Sue you have been noble and courageous throughout and no one could argue with how you feel right now.

take care
