Who decides if you qualify to be a home caregiver and what approximately does a caregiver receive?

I am in a common-law relationship for over 30 years my partner is currently in an inpatient rehabilitation program for 6 months. He is diabetic and over the last year he has been getting seizures as often as twice a month. The medical care he is receiving is through the VA and that is at a cost of $550.00 a month. He has been diagnosed with Hepatitis B also with PTSD. His loss of hearing together with some of his illnesses has caused him to not be able to drive and prepare meals. I have not been employed outside of the home since my father passed away last October, I had been carrying for my dad and my partner and father of my son is going through the same issues. I need help with financial. I was told that there are programs that can pay a family member for assistance. I am sorry to sound so blunt but I never imagined being in this situation. Any help is greatly appreciated..

Thank you
