How do I get my iCloud account back?

[cdraug2]

Ok so here's the deal.. I recently upgraded my phone from an iPhone 4s to a 5s. I was able to sign in to my iCloud on my 5s and everything was going fine. I deleted all of the content on the 4s because I was going to give it to my sister. Well, when I gave her the phone, she was in the process of programming the phone and when the iCloud step came up, my email was still attached. So it made me sign in to the 4s phone, so I did. Well, it asked for a new iCloud account and that was when she created her own. However, I began to get notifications on my 5s saying that her number was now linked to mine and after she had got done the programming process on the 4s, it synced all of my pictures and contacts to her phone. So we decided to restore it again and start all over. So after we started over, I noticed that my iCloud account was deleted. I called apple for assistance, however they were absolutely NO help. So I ended up losing all of my pictures, contacts, games, and iCloud/Apple account. Well my biggest problem with me losing my iCloud account was that my phone and laptop was synced to the "Find my iPhone" account and I was not able to use iCloud anymore. I was forced to create a brand new iCloud account. Is there anyway I can get my old iCloud account back? Or is it too late? This is very important!! Someone HELP ME PLEASE!!
