Need help for my father's memorial

My name is Tammy Schmidt , My story is this... On March 5, 2017 my father Ronald Schmidt had a massive heart attack without signs of any problems it was sudden and a complete shock that 90% of his heart was gone ! After surgery and a long recovery we were told he would be fine and could live a good rest of his life! At 70 years old he was stronger than most people his age. Problems arose and again was in the hospital till this one doctor got his meds right! He was active again and back to what he loved! The ocean, drawing and being with his family. We were so happy he was himself again! Then our worse nightmares came true, on October 2 everything was fine he was sitting in his chair watching a movie with my 7 year old son( his Grandson) I heard my mom screeming for me, I came running , my son was screeming He was just gone! We did compressions until the paramedics arrived, they shocked his heart they got a pulse but hut he wasn't breathing. They took him to Sutter Delta and gave us the news that the machines were keeping him alive. We knew his wishes and took him off life support we were all there for him. It WAS the hardest thing I've ever seen or had to do! My mother and father have been together since they were 13 she is barely coping. My father's only request was to be cremated and his remains be scattered in the Fairlon islands. My mother has been through so much and now is unable to pay for expenses for his wishes .She is unable to survive on her income. They took his dad from her and his Retirement from her!  I am not one to ask for help especially money, but I want my mom not to worry about this I want to help her with money but no one has enough to cover this cost. She needs help his social security was their main income and is now gone. I am a proud person but put pride A-side when it comes to my family. We just need help PLEASE Thank You The last thing my mom needs is these problems while she's grieving.
