From Writers Helping Writers:
Debilitating fears are a problem for everyone, an unfortunate part of the human experience. Whether they’re a result of learned behavior as a child, are related to a mental health condition, or stem from a past wounding event, these fears influence a character’s behaviors, habits, beliefs, and personality traits. The compulsion to avoid what they fear will drive characters away from certain people, events, and situations and hold them back in life.
In your story, this primary fear (or group of fears) will constantly challenge the goal the character is pursuing, tempting them to retreat, settle, and give up on what they want most. Because this fear must be addressed for them to achieve success, balance, and fulfillment, it plays a pivotal part in both character arc and the overall story.
This thesaurus explores the various fears that might be plaguing your character. Use it to understand and utilize fears to fully develop your characters and steer them through their story arc. Please note that this isn’t a self-diagnosis tool. Fears are common in the real world, and while we may at times share similar tendencies as characters, the entry below is for fiction writing purposes only.
Fear of Not Fitting In
Notes
As social creatures, we all have a basic human need to be loved and accepted by others. This requires us to be able to fit in with the people around us. When your character is unable to do this or they worry about failing in this area, their need to be accepted—in general or by a specific group—can become an obsession.
What It Looks Like
