They were created by a British artist to help manage her own anxiety.
Everyone grapples with anxiety from time to time, but for illustrator Gemma Correll, it’s a longer, constant battle. That’s why she started making funny comics to cope.
While Correll is British, to give you homeland perspective, anxiety disorders affect 18% of the adult population (40 million people), making it the most common mental illness. As such, many treatments and coping methods are available both clinically and homeopathically, but since anxiety can manifest differently in everyone, nothing is a surefire fix. Thus it falls to individuals to perform a lot of trial and error.
