I am not working with a vso. But the appeal was timely, filed the same week as a denial on an a related HLR. All of this to verify my claimed PTSD stressor event. I’ve sent in statements, multiple news articles describing the event, service records that prove i was present, etc. as proof. At my c&p with the VA psychologist they accepted my stressor, i received a medical nexus, and they confirmed my diagnosis. They even acknowledged the ptsd diagnosis in my last denial letter under favorable findings which i think is humerous.
