look up any word, like tribbing:
a mental condition in which a person believes s/he has abnormally high levels of blood sugar without having any real physical symptoms; a person diagnosed with the state or condition of psychohyperglycemia is called psychohyperglycemic

Barbara's psychohyperglycemia keeps her from enjoying her life as much as she could.

Because Bill believes he has high blood sugar, but really does not, his psychiatrist labeled him as psychohpyerglycemic.
