How does Stoic philosophy help manage anxiety and stress?

Stoic philosophy helps manage anxiety and stress primarily through its central distinction between what is and is not within our control. Stoics like Epictetus taught that we should focus only on our own thoughts, judgments, and actions, while accepting external events we cannot change. This reframing reduces anxiety because we stop fighting reality and instead direct energy toward our responses. Stoicism also encourages negative visualization, briefly imagining worst-case scenarios to reduce their emotional power and build resilience. Marcus Aurelius promoted examining whether a problem is truly harmful or just uncomfortable. By treating obstacles as opportunities to practice virtue rather than threats, Stoics developed a stable mental foundation that modern cognitive behavioral therapy has actually drawn from significantly.
