How do I get caregiving support while caring for my fiancee?

dont know where to begin, Reality sometimes bites,  i guess its just how hard we bite back that counts

I will be my /fiancee care giver through the rest of stage 4 adeno carnoma  pet scan full body ro see how it has affected brain spine heart and other vital organs, tommorrow of course dealing with denial ,anger, frustrations , verbal abuse  but there is only limited verbal abuse accepted 

I was a caregiver for 13 years inhome 24/7 for my mother and my mother-in-law both lived in my home 85-78

until death one on hospice and the other homehealth.  So i know the routines well   the up[coming downfall and regession.

I need all the caregiving support while i support and care for him.   need to figure out how to get pd. I know they offer any suggestions?
