I have a degree in psychology and know MBTI and Enneagram well too. In psychology, you could make a pie chart where the middle was completely "normal" and each section of the pie, lets make 9 slices, one for each personality type.
As you get stress, you move to the outer edge of the pie, more toward mental illness. Moving toward the center would be your relaxed state. Now if you could put a mental illness on each slice of the pie, or even crossing the lines of 2 types, you could find a mental illness for each personality type.
