My father has just been diagnosed with Coronavirus. He was already in hospital very unwell with under lying issues and is now in isolation. My mother (his ex wife) was staying with me at the time and visiting hospital with us. She is very anxious (aren't we all?) and has just left - I assume to go back home She hasn't left any message and isn't answering her phone. I am feeling very let down. I need help and am feeling very alone. I also think she should be self isolating . Unfortunately this isn't the first time she has let me down - I do appreciate she is scared and anxious but I think this is the final straw. At a time like this I had hoped we would support each other - but obviously not. AIBU?
