Sour Grapes,
I am sorry to hear about your cancer. I have nothing to offer, and I do not know you, or the details of your diagnosis, but fight it, fight it with knowledge, and learn everything you can, and question every doctor, and treatment they offer. Doctors are not some genius wonders to behold as gods, and they will never have the same level of motivation as you do, because they don’t have the same prognoses. Use them as tools, but in the end, it is your life on the line, so fight like it is.
I do understand your anger; however, it will serve no purpose in the end but to spend precious time vexing on something that spawns negative thoughts. Spend that time with good purpose. I realize you don’t care to hear this, but there is a mind, body, and spiritual connection. Whether it’s placebo effect or something greater that we cannot fully yet explain, I have attached a few relevant links, one including a medical study on this subject, and an article from Harvard Medical School. I wish you best.
