Question for The Simpsons: Tapped Out

Signed out of my origin account making a new account to play with while I waited for my orginal simpsons tapped out account to be done with the things I got people to do instead of not playing the game for a couple days but when I went to sign back in to it it said I had the wrong password witch I did not but I followed the recovery of password steps anyways and after I changed it it led me to another thing afterwards asking me to make another account I tried with my original account name but it said it was taken so I made a new name and poof now my towns gone the account on the email is different and my old account seems to not be hooked up to any email any more thus stopping me from signing into it, my girl friend plays it with me and she can still visit my Springfield but the email I used to start it up is now on another account?????? Sooooo choked and would love for someone to explain how smthing this could happen!
