How can I reactivate my facebook account?

[thankfulcoil787]

My problem is because of the fact that when my sister recently created a facebook account and as we share an email address, she added our address as her contact email.
However, now my original account has apparently been deleted, and I cannot access it, even though she has changed her contact email to an alternative.
My account was very important to me as I have lots of pictures and contacts through the account.
I have emailed various facebook email addresses, and I either get an automated message or just ignored.
Has anyone gone through this, and got their original account back properly again?
I really don't want to make a new one, and anyway thats against facebooks rules, unless I create another email address.
Any help would be much appreciated. Thanks.
Well no I can't log in because it would want my sisters password, not mine. But shes changed her log in email to something else now anyway, so the original email address doesn't work with any password.
I think that what you mean by reactivating is when you haven't been on your account for a while and then you reactivate it if you know what I mean. Thanks for the help though. x
