I technically meet the full definition of BP-2 now -- and after a traumatic brain injury.
I have had a diagnosis of severe PTSD/CPTSD along with "atypical depression" most of my life.
I have a few autoimmune conditions, along with severe chronic pain.
The change to BP-2 may have been related to the actual brain injury and/or the stress related to the random assault which caused the brain injury.
