Step1 Head to the Facebook Web site to reactivate your account. Step2 Log in to Facebook as if you'd never left. Use your original email address and password. Step3 Check your registered email account for a confirmation email from Facebook with directions on how to reactivate your account. Step4 Follow the link in the email. You will be taken to your home page, which will appear exactly how you left it. All your settings and events are intact upon reactivation. All you have to do is start exploring again.

This is because your account does not actually reactivate and it simply creates an account with the same name but a different digital signature. unfortunately you will be unable to edit stuff from your previous profile.

I would recommend you to visit a website called Facebook Disabled. It explains in detail on how to get back your account.

You're just going to have to make a new one...you can still use the same email address since it's deactivated, so if it says that the email address already exists, then you have to reactivate it a different way.
