Sorry, but I don't quite understand why you're posting that here. There's nothing anybody here can do to help.
If you're sure that you haven't violated Facebook's TOS, then wouldn't the best thing be to contact them and ask them to reinstate your account?
Yes, definately take TechnoBear's advice.
The did not cancel my account. I did have to "prove I was me" though.
Facebook won't delete your account for one month duration gap unless otherwise if you request for account cancellation.
