Imagine saying to somebody that you have a life-threatening illness, such as cancer, and being told to pull yourself together or get over it.
Imagine being terribly ill and too afraid to tell anyone lest it destroys your career.
Imagine being admitted to hospital because you are too ill to function and being too ashamed to tell anyone, because it is a psychiatric hospital.
Imagine telling someone that you have recently been discharged and watching them turn away, in embarrassment or disgust or fear.
Comparisons are odious. Stigmatising an illness is more odious still.
