First, you're not alone in falling victim to a Facebook account hijacking. Facebook is a big target for hackers and scammers. Think about this: Facebook has 2.989 billion monthly active users worldwide.
Your first step: Go to Facebook.com/Hacked and alert Facebook that your account has been compromised. You'll need to enter your email address or phone number associated with the account. Be sure to give every bit of info they ask for.
Next, contact your friends. You'll have to do this outside of Facebook, of course. Tell them your account was hacked and ask them to do you a huge favor. You want them to also report to Facebook that your account was hacked.
