Going out of my MIND

I had mentioned a quote to my friend, and she seemed positive the movie I quoted from childhood was "The Secret Garden." Now, I watched the first scene on youtube, and I'm positive it was not.

GOING CRAZY TRYING TO REMEMBER!

There was, I believe, a plague going on. There was a spoiled little girl and her parents. She wakes one morning to find her maid dead, and goes to her parents bedroom to say, "[name] is dead, and there is no one to dress me or feed me breakfast."

Her parents are already sick, so she goes to where the party the night before had been to eat the food, and she gets sick (less sick). The parents die, and I vividly remember her being taken away and her teddy bear burned because it was tainted with the germs.

Unfortunately, that's all I remember. Any help?
