covering costs of my grandpas basics needs

So as some of you may know my grandma had been severely sick and in a hospital bed the last few months.  On 10-14-20 heaven gained her beautiful soul. My grandparents mean the world to me and I am trying to help out as much as i can by starting a gofundme to raise money for my grandpa and uncles food and basic needs. They don't know I'm doing this because I'm trying to keep it a secret. Every penny helps and is appreciated.
