I'd be confident with your long run milage that you'll be more than fine for the half. Just don't go out to fast, try to run as fast or slightly faster the second half.
Not that I recommend it, but I ran my 2nd half yesterday and my long run the last 4 months was 8 miles. The guy who was second in the full had never ran a full or half before. Might be extreme, but just saying.
