Help me bury my fiance no one wanted to sale to us

Roy and I met 8 years ago when I was fixing to move home to Vinton Louisiana he had a heart attack and nobody was helping him and   one day we was talkin and I promised my mama that I would move home to take care of my little handicap sister when she passed away and that's what I was doing I told him I was moving in a week and if he wanted to come home with me I'll take care of him even though he don't know me and I don't know him but I'll be there and I've been taking care of him for 8 years we came into the hospital for some antibiotics and yesterday he code blue and now he's on life support and his wishes is not to be on life support I tried to buy insurance for him but since he has an lvad which is a mechanical heart he lived on electricity and batteries they would not sale us any This is killing me to ask for help but I thank all that will God bless all
