All of a sudden I can't look for anybody. AT the top where I would put someone's name I get a drop down menu that says looking for friends...
Looking for... looking for different things but won't let me put in a name.

Also I found at the top where my name usually goes and I click to get onto my own page, my full name disappeared and it's only my first name. I'm so
Upset because I use Facebook a lot and need that box to contact people.
I hope you can help me. I'm so technically challenged it's pathetic.

Hello, Facebook does this to me occasionally. What browser are you using? I reckon clearing your cache, cookies and history should help. If you're using Google Chrome; try this: press crt + shift and delete all at once. This should bring up the history page. Check everything (except saved passwords, if you want to save them). Select from the begging of time and hit delete. Close Chrome, restart it and Facebook should work.
