Worried For Her Life

I'm very worried for my mother's health at the moment. She hasn't eaten any food in over a week now, and whenever she does eat, she has a singular mouthful per day. My carer is worried she has cancer.

My mum has never prepared me for what happens if she is to die. I'm disabled, and very lucky that my carer has been living with me for a while now. But my carer does have a life. And if she has to leave, I don't know what I'll do. I rely so much on her to be a maternal figure, even though she is only a year older than me.

What should I do? I'm so scared. I'm at breaking point.
