I was surprised by the post treatment depression. I had a good response to my chemotherapy for pancreatic cancer and went from borderline resectable to resectabal. I had surgery and had no residual cancer detected. Seems like I should be on top of the world. My therapist explained it like this: during treatment everything is focused on making it thru the treatment with a lot of adrenaline. People called often and gave support after treatment was going well, the calls stopped Afterwards, the adrenaline and focus disappeared. A kind of PTSD seemed to set in. I asked myself. "where did my life go anyway?" It was also suggested to me to get busy. I don't want just to be busy, I want to feel like I have a meaningful life. When I was well enough, I started volunteering at a local food pantry for 3 hours a week. I was amazed at the uplift I experienced. Seeing so many struggling just to get by I feel so fortunate. I am glad to hear your story. I thought I was alone.
