A year ago I lost my Dad to cancer. It came as a complete shock and things happened very quickly. Within 3 weeks he went from being mildly unwell (misdiagnosed) to passing away. His decline was very traumatic but we stayed with him 24/7. I'm really struggling with flashbacks, particularly related to him begging us to help him. We couldn't help him as all he wanted was not to die. I thought time would help but a year later I feel just as bad as when it happened. Any tips for coping with flashbacks?
