Trouble adding an Else Statement

I’m having trouble adding an Else to this loop. It won’t validate 🙁

<?php
//if a certain page, then display posts authored by the logged in user
  global $current_user;
  get_currentuserinfo();
  echo 'User ID: ' . $current_user->ID . "\n";
  $args=array(
    'author' => $current_user->ID,
    'post_type' => 'wpbdp_listing',
  );
  $my_query = null;
  $my_query = new WP_Query($args);
  if( $my_query->have_posts() ) {
    while ($my_query->have_posts()) : $my_query->the_post(); ?>
      <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>

     <h1>
     <a href="/therapist-directory/?action=editlisting&listing_id=<?php the_ID(); ?>
">Edit Your Profile</a>

     !</h1>

  <?php endwhile; else: ?>
<p>Sorry, no posts matched your criteria.</p>

 <!-- REALLY stop The Loop. -->
 <?php endif; ?>
