I have been diagnosed with bipolar since 93. A doctor recently switched me from clonazepam to Valium very abruptly. It was horrible. I was also switched from citalopram to Cymbalta abruptly at nearly the same time. I have now been switched back, but don t feel the same. In fact, much of what I m feeling coincides with descriptions of symptoms of borderline personality disorder. Is it possible the medication change triggered BPD in addition to bipolar? If so, could it be permanent, as I fear? Is it possible these symptoms are from just readjusting back to the old meds? (Sorry, three questions for the price of one..).
