What whining? Compared to the way that I bitched & moaned, your very reasonable dissatisfaction with being transmuted from super healthy to Cancer patient simply does not rise to the level of whining. It is hard to believe that in the 21st Century, the "best" therapy available is to dissect you and then literally burn your cells and then poison them. The TX is barbaric.
As for taking action to help yourself get thru this TX, OCF calls this "adjunctive therapy" not alternative since it does not replace surgery, rad,& chemo. Everyone varies, but yoga, meditation, pilates helped me. True, I had to quit the formal classes and rigorous practices but I could still do "mountain pose" etc. I did quit the weight lifting entirely though during TX as just getting off the couch for radiation was exercise enough at one point.
And yes, I still wake up some mornings and fervently hope that this was all just a bad dream, but as you are finding out, it's all too real. But just read this forum and see how many people have gotten thru this- you will too
