I had this car accident two weeks ago. I was 100% at fault. I’m a resident doctor and decided to visit my parents post call - stupid idea. I had a momentary lapse in concentration, took a faulty turn and was t-boned. No one was hurt, but both cars are likely totalled. I’ve been feeling worthless and absolutely incompetent since. I’m losing concentration and interest in work, and I keep thinking back to the accident and how it was all my fault. How the hell do I move on?
