Hello, my story

My grandma of 82 is increasingly deteriorating with cancer....she was diagnosed 4 weeks ago and the family have been looking after her, sorting medication, washing her and making her meal's...the family are exhausted as we have jobs/children etc...and are now feeling guilty for asking for help...I do personally think she needs professional help...but don't want her thinking we have given up. 8 weeks ago she was tootling around in her car having tea and with her friends...it's all happened very suddenly...
