I was diagnosed the first time as a teenager after a manic switch from an antidepressant. I was hospitalized a year or so later due to severe depression and psychosis. After a few years I ditched psychiatry entirely and thought my diagnosis was wrong. Turns out I was wrong. After some years of remission my moods got worse. I was originally diagnosed with depression but that quickly changed to bipolar again after a manic switch from antidepressants.
