Mum terminal lung cancer

Hi everyone I’m the oldest of 5 kids I’m 39 and a nurse

my mum is really ill with end stage lung cancer she should be getting oxygen this week nurses are going in an out just having a chat with her my dad stays so many nights a week an other nights she’s alone I feel terrible an riddled with guilt I can’t drive so can’t be there all the time wish I could but I have work an 4 kids 

sometimes I feel like quitting my job but even that won’t help because the kids still need to go to school it’s just so hard juggling 

I don’t know what to do
