I can't get on my Facebook! When I enter my phone number someone else's account comes up!! I don't remember the password to my email account that is associated with my Facebook and I don't remember the original phone number associated with account! I have tried my trusted contacts and they gave me codes but they don't work so I asked them again and it gave same codes!! Please help me!!

Have you tried the recovery options ?

Oh geez. Sad to say, same thing happened to my previous account and I literally didn't recover it even I also did everything fb suggested.
