My friend, Susie accidentally hit an old lady who was crossing the street 2 months ago. The poor woman was rushed to a nearby hospital and luckily survived. However, there are some fractured bones that need to be treated. Tho the old lady is getting better, my friend is still feeling guilty. She even lost some pounds due to stress and overthinking. I think she was one the who got traumatized. How can she overcome that guilt feeling?
