It is so sad to see that your Mum's diagnosis has caused such division and petty arguments in the family, when really you should all be concentrating on her and her happiness in the coming days - if as you say that is all her prognosis is.  I am glad to see that you all spent Christmas with her and I hope that you made memories to cherish. 

I can understand your Dad not feeling safe to deal with Mum's death alone at home - it would be a massive responsibility for him  to cope with if you and your brother are so far away and unable to be there to share in her care.  Not everyone feels able capable to deal with such a harrowing experience without reliable support.

I am sure you feel torn and also hurt that your husband is so unsupportive at such a distressing time - it seems odd that he would be fed up with seeing you cry -  how else would he expect you to be if you are losing 'your Mum and best friend'?

If your Mum's prognosis is days as you say - is there not a way you can stay with her next week and offer your Dad the support he so obviously feels he needs too?  Please ask the nurses on the ward to connect you to the McMillan Nurses or Palliative Care Team at the hospital who will offer you all their help - as a family - so that you can stay united and be there for your Mum at the end of her life.  This time should all be about her - not silly family squabbles that you will later regret.

My thoughts are with you all and I hope you can sort things out and concentrate on your Mum asap x
