Help Andrew Care for His Ailing Mother with cancer

Hello, my name is Andrew , I am a caregiver the mentally and physically handicap, but very recently, my elderly mother who has Parkinson's has also been diagnosed of stage 4 colon cancer. Along with her Parkinson's this causes her to have extremely low blood pressure and to pass out randomly ,so she needs to be constantly watched and taken care of. I'm glad to do so but I'm now also unable to work in can't pay bills. So I'm asking for some help. I actually get paid good at least I think so around 800 mouth , but can and haven't been able to work
