Input: the feeling in the user's own words and/or one of the seven topics. Output: up to four prayers, each with its Bible passage (NIV), the prayer text, and a link to that prayer on godismysanctuary.com. If the feeling matches no topic, it returns the list of topics instead. If the text describes suicide or self-harm, it returns crisis resources (988 and Crisis Text Line) instead of a prayer.
