Cant log in my account

Hello, .I had a facebook account from my email adress (***@***) naming Hammad Aslam.I was also managing my business page from this account.
Few days before, i made another account from my same email adress (***@***) with different password and name.Now when i am trying to open my previous account naming Hammad Aslam so it is not opening.I did'nt knew that from one email adress only one account should be made. Know i have lost my previous account that was so important for me as i was managing my business page from that account.
Please help me to recover my previous account, i can give up my new account to recover my previous account Hammad Aslam. Please reply me soon i am in great trouble.
Thankyou!
