My friend is ruining my life! Help!?

So my friend from Atlanta visited our neighborhood for a day and is about to leave. I was looking forward to spending time with her, but two of my other friends are mad at me for some reason. I don't even want to go say goodbye to her because my other friends have given me enough. One of my friends is only like this around my other friend. They are the only ones I have to hang around, but I can never seem to get along with them. I have had the worst two days of my life. What should I do? Help!
