Trauma & Polyvagal Theory
Trauma is subjective meaning, you can experience trauma without falling under a diagnosable label. In fact, I believe we've all experienced trauma at some point and it is the individual experience and the loneliness in that experience that defines trauma, not the type of event. For example, a child falls and no one is there to scoop them up and say it is going to be okay, being bullied by other children or family members regularly, or never feeling allowed to have personal needs. Our biological temperament, what we experience, our age and how often we experience the threat contribute to unprocessed events and future perceived threats.
Clients do not need to have a trauma diagnosis to benefit from EMDR and parts work, and I use aspects of EMDR and parts work.
