A Daughter wanting to ease my father’s grief after losing his only son

Hello. I would like to raise money for my father. He only had 2 children me and my brother. My brother died from a sudden heart attack on October 30/17. He was in a coma for a month in Vancouver BC. My dad lives in BC but 1000 miles from Vancouver. He had to travel to be with his son. Pay for his way and now he is depleated financially and grief stricken of losing his son. My dad is 78 years old. A widow with no family close as we live in Manitoba. He is sick with bad asthma. Im worried for him. I would love to go be with my dad but cant afford to go. My dad needs help and i can only try this as i dont know what else to do to try and ease his pain.
