How can I optimize this postgres query? Social Media Feed (posts, comments, replies)

I wrote this monster sql query (at least it's massive to me as someone who doesn't usually touch sql), and I feel like I'm almost 100% doing something inefficiently here. Would love any opinions on how I can improve this.

For context I've been working on a query that in the end should return a total number of posts, posts, comments for each post, total comments count for a post, the first reply to each comment if they have one, and the total number of replies to each comment. Only allowing comments to go one layer deep.

Here is the query:

   SELECT
    COUNT(*) as "totalCount",
    array(
      SELECT
        jsonb_build_object(
          'postID', p.post_id,
          'userID', p.user_id,
          'textContent', p.text_content,
          'thumbnailImage',p.thumbnail_image,
          'title', p.title,
          'createdAt', p.created_at,
          'displayName', c.display_name,
          'profileImage', c.profile_image,
          'isLiked', (SELECT status FROM PostLike WHERE user_id = $1 AND post_id = p.post_id),
          'likeCount', COUNT(l.post_id) FILTER (WHERE l.status = TRUE),
          'commentCount', COUNT(DISTINCT co.comment_id),
          'comments', array(
            SELECT
              jsonb_build_object(
                'comment', jsonb_build_object(
                  'commentID', c.comment_id,
                  'createdAt', c.created_at,
                  'parentID', c.parent_id,
