I'm so angry.

My cousins funeral is tomorrow, 3 and a half hours from where I live. I have been trying all day to find someone who could take my kids. I need someone to pick them up from school at 2 and sit with them for a few hours. The only people who have even said they would like to, can't. One doesn't drive, and the other has two kids of her own and only a small car, not big enough for four kids. Why? Why do we have huge families and not one person to count on in this situation?? If it were someone in his family so many members of my family would be willing to take our kids. But everyone who could take them, are going to the funeral.
So angry.
