WHAT DID I DO?

I’ve been enjoying Facebook for about 5 months. I post regularly and always adhere to the rules. I was locked out of my account and a message said that “due to unusual activity on my account” I needed to put a code that would be texted to me in to insure that the phone number associated with the account is correct. WHY?!?! WHAT UNUSUAL ACTIVITY?!?! Now the code never is received and others say my FB is gone or just blank. I’ve been waiting on that code for 2days now and nothing I do works! I guess I just no longer have a Facebook account. ??‍♂️
