My dad is 72 and is suffering from alcoholic dementia - he has been in and out of rehab but starts drinking again straight away. My mum is trying to help him but is always angry and now out of the country for 3 weeks. She also works away during the week in London. He is confused, smelly, dirty and keeps being found by the police having fallen over. He has seen the best medical professionals and had all the treatment - but nothing sticks. I am coming to the point of getting into his house and checking he is alive and leaving him. I don't know what else I can do. My relationship with my husband is struggling as I work full time and have a 15 year old daughter who also needs me! He was not the most supportive parent and suffered from mh issues all of his life. I feel so guilty. What else can I do?
