It sounds to me like you are not getting help by the right professionals who understand trauma recovery and PTSD. Many professionals actually confuse the symptoms of PTSD for bipolar. There is a huge difference between hyper-aware and hyper-vigilance and anxiety attacks from a manic bipolar episode.

With PTSD there are times where an individual is experiencing a trigger or hypervigilane episode, then falls into a more tired depressive episode, this is NOT bipolar.
