I personally do not think antidepressants triggered bipolar disorder. I think the wrong antidepressant can certainly exacerbate bipolar or schizophrenia but I do not think they can cause them. I can say IME SSRI's are not good for bipolar. I believe that SNRI's are more effective and that they should be combined with a mood stabilizer. I also think an antipsychotic is essential even if you do not have psychotic symptoms.
