Whats going to happen to my dog? Is she going to be ok?

My dog got to my Halloween candy. She ate 3 fun sized packs of M&M's, Laffy Taffy, 1 fun sized pack of Skittles, and 1 box of Nerds. What do I do. Is she going to be okay? She is a female boxer and is 8 years old. Please help me. I don't want anything to happen to her.
