Lost Account to Lightroom Account

Hey, I'm Mariana. I've lost my phone and all the pictures that I had with it. I have a new phone now and just created a new Lightroom account here, but I'd like to know if it's possible to access my old Lightroom account even if I lost the access to the email that was connected completely? 
is there any way that I can prove that account is mine? 
The issue is my previous account is connected with Facebook that is connect with an email that I have no access at all anymore, so I can't recover the password to log in again. 
All my pics are there, this is my only hope. Thanks!
