Just because the meds were not working does not mean anything, for there can be several reasons for this where you can still be bipolar. I think as someone suggested the doctor can start out by medicating for the symptoms. In you case, this would be depression. But you need to stay with a doctor for treatment, particularly if this condition is preventing you from functioning in your life. I suggest to not play "doctor" with your medication. You do not have the edjucation and training for this. Instead, talk to your doctor about your concerns.
