Generation Codes Facebook? Help.?

[Chelsea]

How it works, when you sign in to your facebook from an unknown device Facebook will send a SMS with a code you need to type in to log onto your account.
At the time it seemed like a good idea to put this code thing on Facebook so that only I can access my Facebook account from my phone. I only ever used Facebook on my phone so I have no other known device to my Facebook. Very recently, I lost my iPhone.. without my phone to text and call, Facebook is really the only other way I keep in contact with family & friends and to make arrangements for college and the weekends. But without my phone I can't get access to my text messages to get the codes to log into facebook. I have filled in the report on facebook but have had no response.. So i resorted to Google, many people have had the same problem but months later they still can't get into their account and this worries me because I have so many picture memories that I can't get back, so now I'm here looking to see if anyone has any suggestions of what to do or if anyone has been in a similar situation and knows what to do..

I really hope this makes sense, and thank-you in advance.
