Palliative Care what is their role? It feels like we've been left to look after my dad by ourselves

Hi

My dad was discharged from hospital 3 days ago with no treatment as his cancer is now terminal. He has LMD.

My dad can’t stand or walk now. He isn’t eating or talking. The carers are saying they can’t get him out of bed now so they can’t really do anything more. We don’t fully understand when we should be giving him the oramorphe as it’s just says ‘as required’ but dad can’t speak to tell is if he’s in pain but no one has given any guidance dad was just sent home with a bag of medication that has conflicting instructions on them. 

We were told we would get support from Palliative Care but we had had to chase it up as no one has been to see dad and check on him since he left hospital 3 days ago. When I spoke to them the lady was quite detached and was saying there’s a capacity issue and if we want she would try and come tomorrow. Is this normal? 

My dads practice manager from his doctors has just rung me and said this palliative care nurse rang them and tried to push dads care onto them and she also agreed she was very detached. 

Is this normal or should we have had support by now?
