My grandma just died?

My aunt litteraly just called 5 minutes ago and told me my grandma died and im the only one home so now i have the job of calling and telling everyone while my parents are at work. Yesterday the nurses called and said they thought she was going to die yesterday but only my dad could go because i had a softball game and now im realy regretting not going because ill never see her again but my dad had called me and told me that she was doing a lot better so i thought she was going to be fine. how do i tell my parents.
