Can i get tested for bipolar disorder at a walk-in clinic?

I doubt it: There may be more than one misunderstanding here. 1. There is not a "test" for bipolar. The diagnosis is made on a detailed history of mood episodes. 2. Walk-in clinics are not likely to have a psychiatrist or psychotherapist and while, unfortunately in my opinion, some gps do prescribe medications for mental disorders, it should not be done at a walk-in where they hardly know you at all.
