Nothing stands in isolation, and that is especially true of trauma.
Most usually current traumas are preceded by early forms of the same thing; there is a progression of occurrences and the emotions/thoughts that have been attached to them. If we address and clear the present struggle its more complete resolution is most usually found as we follow the energy to the early places. Once visiting, clearing and reframing those energetic aspects that are alive and functioning in our subconscious the present challenge frequently resolves very quickly.
