Someone tried to login to my account. Now i can't get in

On July *th I got a facebook notification on my phone. Thru text saying someone had tried to login to my account from the Dominicain Republic. I live in Missouri. I clicked that it wasnt me. Then tried to get on my fb account thru the fb app on my phone that i am always logged into. I never log out. It said my session had timed out. I tried to login and it said i needed to change my password. I did. Then it goes straight to "need login code" it says it is sending the code via SMS. But i never get it. The code that was sent to my email just wants another code (still not getting the SMS). I even tried verifing it was me by sending a pic of my ID. They sent an emaio back with a change password link. That link still wants this code i never receive. Plz help. I cant lose axcess to my account. A decade of pictures of my kids. And deceased husband and mother. No copies of those pics anywhere else. This is devastating!
