My mum has been in hospital since boxing day. She was in Intensive care but is now on a ward since Friday. Physically she is getting stronger but her mental health is really worrying me. Her personality has completely changed. She keeps saying strange things like she needs to get out as the nurses make her climb the walls while the building folds up. She has no emotion. Her memory seems fine and she knows who we are. The doctors just say it is early days but I can't help but worry as I really miss my mum and worry she will never be the same again. Is this normal?
