My mum has a brain tumour and does not have long left to live. Because I am going away for a week, my step Dad is not letting me see my mum anymore. He has blocked my number so I cannot even call to check on her. They live in Norfolk and I'm in Hertfordshire so it's at least 2 hours away so I can't just go round whenever. I would really appreciate some advice on what I can do to be able to see my mum again she dies.
