All my Facebook Friends have been deleted?

[kate]

This has happened to me today too. Says I have no friends, some of my albums aren't showing up, either is my 'close friends' list, some of my personal info had been removed too and when I go on my news feed only my posts and posts from pages I've liked are the only ones that come up. I've managed to change my password because I thought someone may have been hacking into my account. However when I've asks my friend to see if she can still see my profile she says she can and she can still see all my albums etc. I'm so confused! Does anyone know if its a problem I just have to leave and let fb sort out?
