My dad's funeral costs/autopsy

My beloved father passed away unexpectedly in his sleep 1/28/17. He was only 60 years old. Since this came out of nowhere we don't have the funds to get an autopsy done to see what caused his death plus the memorial fees. I was such a daddies girl. This is one of the hardest things I have had to deal with in my life. I'm definitely taking it really hard. Anything will help.
