I'm58. My partner of 40 years is 73. He has Alzheimers and vascular dementia. I gave up work in march 2015 to care for him full time. He was diagnosed with cancer recently and has completed six weeks of chemo/radiotherapy. He has been left with diarrhoea as a result of the treatment (although no longer as severe as it was). He obsesses about toileting. Consequently I spend hours every day (and night) assisting with real or imagined toileting issues. I feel as though my very breath is being drained from me. What to do?
