Was there are specific symptom that she was alarmed by? I was ordered to stop all medication a couple times because of severe side effects - body going numb and tingley, heart problems, fainting or severe dizzyness. I didnt have many problems with coming off them too fast in most occasions. But coming off all meds while you are still so manic can be bad. Are you or have you ever been on a mood stabilizer or antipsychotic? They may stop the antidepressants from sending you too high.

I would definitely get a second opinion if this has been your cycle for years with the same team. Obviously not working, you can have periods of stability with the right meds and coping mechanisms.
