I was appointed my mom's caregiver through social security and social services. I haven't been paid and I wanna know how I can get paid now?

Mom My mother was demon and competent And once she was , I had a doctor's note saying that I Been her caregiver for the last seven years and one told her death I had done everything I had done everything that social services had asked of me to do except give them the name of a home Facility?
That I would use to get any products or anything that I needed to take care of her And that would be whom that my check would be payable from, my mom passed away Before I submitted what company I wanted to use because her health decline rapidly i put this process aside because mom was failing fast.when I called social service Let them know that my mom passed away.They told me that it null and avoids me getting paid for being her care giver, is this true? And how it doesn't change the fact I had to give up my career and my way to support myself to take care of her
