What kind of experience is it to be misdiagnosed by doctors?

He has been diagnosed with paranoid mental disorder, unspecified non-organic mental disorder (because of delusion), bipolar disorder (because doctors really don't know me) and severe depressive episode (emotional roller coaster), and has been taking medicine for more than three years. Anti-depression, anti-anxiety and anti-schizophrenia all have ... anxiety, depression, delusion, mania and many other symptoms. Over the years, doctors may have neglected my adolescence and endocrine problems. Finally, I went to Peking University Sixth Hospital (the best psychiatric hospital in China) for a week. I thought it was just adolescent psychological problems, endocrine disorders ... I almost stopped taking medicine and was a complete person.
