2 accounts 1 mail

Hi guys, 

When I log in on fb with my mail in logged me into an empty account instead of my own. I deleted my account in the hope to get rid of the empty account and get back into my original account. But I think I might have deleted my whole fb. Anyone know I can fix this? I tried forgot password but don’t get a mail. I tried logging in by looking for my account because it still exist when I look it up but keeps saying I’m using an old password
