It really took a long a time for Bob to get used to his new normal and "lighten up" even after he was physically in good shape. I kept expecting this "I have to embrace life and smell the roses " attitude since he had fought so hard and was cancer free. It was more than a year after treatment before he shook the post treatment blues, they were not severe and did not require medication but subtley he was definitely a little down. I was at first very confused by this until I read of so many others having the same experience here. It helped me be patient but it truly was a little frustrating to say the least.
