twinOP,

Your snapping at your boyfriend IMHO, is more to do with the PTSD than bipolar disorder. I am wondering if you may only have PTSD going on which has cycles to it that are similar to bipolar disorder. Keep that in mind and see if you can read up on that, when a patient presents to a psychiatrist that they are fine for a while then hit some lows, even debilitating lows, it is not unusual for them to be diagnosed with Bipolar disorder, when in reality PTSD has those same symptoms. And PTSD has a variety of symptoms which can lead to misdiagnoses of other disorders when in reality it is all just PTSD.
