Anxiety is a common disorder that many people suffer from on a daily basis. Writing characters with anxiety can be a great way to add diversity to your cast of characters but also a way to make your characters more relatable and feel more reel to your audience.
The art of writing different personality types is one that every writer should strive to master. Writing extroverted characters, as well as introverted ones, can be a great way of making sure your set of characters is diverse and appealing.
Characters with ambivert personality traits are comfortable and enjoy social settings, but they equally enjoy alone time. So, whilst an introverted character may spend 70% of their time alone and 30% with other people, an ambivert character will spend 50% of their time with people and the other 50% alone.
