No Line breaks in my RSS

Howdy, check out my RSS feed in a browser:
https://www.triplepundit.com/rss-full/

As you can see, most posts don’t have any paragraph breaks in them. Or rather, they have very few. Wondering what I might have done wrong? THe code for the <description> section is as follows:

<description><?php echo '<![CDATA['.$post->post_content.'<br /><br /><a href="'.get_permalink($post->ID).'">'.get_the_title($post->ID).'</a>'.']]>'; ?></description>

I do not know PHP, so can’t make heads or tales of that.
