In Epictetus's writings, he emphasizes that the primary source of our fears and oppressions is our own thoughts. We often allow our minds to create obstacles that overwhelm us, particularly when facing significant life changes or transitions. The prospect of leaving behind familiar environments, such as friends and family, can induce anxiety primarily because of the mental narratives we construct around these changes.

Our fears stem from the thoughts we entertain about what lies ahead. When we embark on a new journey or phase of life, our minds can dwell on uncertainties, amplifying feelings of dread. By recognizing that these oppressive feelings originate within our thoughts, we can learn to manage them, paving the way for a more empowered response to change and departure from the familiar.
