Your included file counter/share-count.php defines the shareCount class every time it is included, which is why you are seeing the error. You can fix this by either using require_once() or check to see if the class is already defined using class_exists() and only defining it if the result is false.
Using require_once() to replace require():
require_once("counter/share-count.php");
// ... rest of your code
Using class_exists():
if ( ! class_exists( 'shareCount' ) ):
class shareCount{
// your class implementation
}
endif; // class_exists
