Went to visit dad tonight and it seems that they have done a test and dad has a blocked carotid artery and I have to go in tomorrow to see the doctor as they are planning an angioplasty. Not sure if this is a good idea or not. I know it is a simple procedure and they can insert a stent but I need to talk to them first. Dad was ok when we left. Now just had a phone call and dad won't settle until he know that mum knows where he is (she died in 2011) so I spoke to him and told him that she knows and not to worry. He tested me to verify who I am by asking me questions because he thinks he has been kidnapped. He believed me but I am guessing that he will forget in five minutes and need constant reassuring all night so I am keeping myself on standby just in case. This is all so sad, he has not mentioned mum for a long time only when talking about their cruises. He keeps thinking that he is on a cruise so that may be the trigger. I could not possibly tell him that she is dead and upset him even more. Every time he seems to get a bit better something else happens. It's up, down over and over again and so difficult to help him. I don't know what else I can do. It's all horrible.
