My Facebook got hacked can you help?

[Lahori Munda]

Mostly hackers use their BRAIN. They'll send you friend requests and they'll know your personal things by chatting with you. Like: where were you born or what is your pet's name or where were your mother's born. By knowing that they can easily change your email on Facebook by answering the questions you tell them. They make a new email account and change your email on Facebook easily. You'll have only your Email account left with you.
They won't know your password.
