As an individual who is trying to become a clinical psychologist, I have to state that you have hit the nature of anxiety quite well. It is something that can both help and cripple an individual. You have people who try to drown out their anxiety with various coping mechanisms. Some are healthy, like writing, drawing, or even talking them out with individuals. Others are incredibly harmful to the individual's physical and mental health. Also, the fact you cited your sources is an incredibly lovely touch, in my opinion. I also find the artistic representation you did for the color of anxiety being easily seen on the main three characters.
I seldom come onto Newgrounds looking for something that has a real understanding of psychological aspects. You have gone above and beyond in terms of making this an easily understandable form for the typical individual. You even have fabricated an intriguing way for those in my field to examine this in a singular individual. So, I must say an exemplary job, and that I hope to see more like this in the future.
