Step-by-step explanation:
Katelyn has been experiencing symptoms of depression and lethargy, which are indicative of a mood disorder.

Antidepressants are a class of drugs specifically designed to alleviate symptoms of depression by adjusting neurotransmitter levels in the brain, which can affect mood and behavior. They include various types, such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants. These medications can help improve mood, increase energy levels, and generally help individuals manage the symptoms of depression more effectively.
It's important to note that while antidepressants can be highly effective, they may come with certain risks and side effects, particularly for young people under the age of 25. Therefore, these medications are typically prescribed with caution, and patients are monitored closely by their healthcare providers.
