People with actual psychiatric illness are at the mercy of delusions/ hallucinations etc. So schizophrenia, bipolar, psychotic depression. Their beliefs are not aligned with reality - Major Psychiatric Illness. They could believe voices are speaking to them and commenting on their actions - in a very critical manner. But they don’t have insight that this is not true.
Other conditions - anxiety: less severe depression- people know they are unwell, and their beliefs have founding in reality. They develop anxiety about things they know they don’t like - even if they don’t know the exact reason - their reasoning is not distorted.
In my view the awakening of understanding about Mental Health, has affected our ability to understand and be empathic about Mental Illness. Much easier to speak about anxiety, than irrational psychotic delusions that you see know point in discussing because you believe them to be true.
Again, I am speaking in general terms about the difference between Mental Health and Mental Illness - in my view.
