Facebook problem!!

Facebook is working for me, kind of,. It won't let me send messages, or look at them. I can't look at my chat list, and when I update my status I don't have those little icons on the bottom. Plus, the notifications just stay there even after I look at them. It keeps adding up; "+1 , +2, +3, etc." Does anyone know what the problem is?? It's been like this for 3 days for me!!! HELP?!
