It pains me to continue reading stories like this. Facebook and Google are absolutely awful when it comes to account protection, and it's crucial never to use these products to authenticate against any services that matter to you - there's literally nobody to talk to, and a million insane reasons why they might shut you out of your own account!

I cannot recommend the following warmly enough: make sure that you own your identity (ie sign in to services with your own credentials, and make sure you have full control of the email addresses for your accounts), and use a password manager.
