He is starting to get quite poorly now and feeling overwhelmed with everything, I want to take some of the stresses away. I know having to ring for help, advice and appointments is getting to him. When I've tried, they refuse to speak to me. We don't have a POA and my dad is single and lives alone. Is there anything with can out in place quickly, or a form we can compete with the hospital. It will be me and his sister who are supporting him.
