whats wrong with my facebook homepage and profile??? :O(

I am at my wits end!! My Facebook homepage has been blank apart from the top left hand corner and live news feeds bit. Also my profile page is all over the place. I can use the inbox, go to my friends page and apps, and use the chat option when on those pages, but no homepage!! Ive notified Facebook and had absolutely no feedback and nothing has been done. What is going on?????
