Sorry to hear about your dad. 

To be honest the delusional or confusion part could be a number of things. If the bodies starting to shut down then this may be a reason why he is behaving this way. It's possible about it going to the brain however it may not be that at all. Best person to ask would be his doctor. Nobody on here can give you a definitive answer. My experience is a bit more definite because we actually know the reason for his confusion. My dad was diagnosed 2 years ago with stage 4 incurable bowel cancer which has spread to his lungs and liver. 7 weeks ago it travelled to his brain, he also has a mass behind his left eye and is classed as terminal now. He becomes very confused and disturbed at times. This is due to the cancer affecting his brain and his way of thinking as well as his overall behaviour. As for support groups it's worth contacting macmillan or maybe a local hospice as they can offer support and may know of groups you can join. Unfortunately when it comes to help and support I don't feel there's enough of it for the families x 

Thank u for your reply Hun sorry u are going through this to we haven't had any support so far but the Mcmillan nurses are coming in today to talk to us as the district nurses thought we needed to speak with someone u seem to get more support if your loved one goes into s hospice. X

Hi, did you manage to get any support from macmillan? How's your dad? And how are you coping? Sorry for late reply I've just logged back on x
