I am glad you are without disease, and if you believe that "loving yourself" did that for you, you are free to say so. Just as others are free to disagree.
The problem with your post, well intentioned though it undoubtedly is, is that it implies that the rest of us are, well, deficient in some way. Not spiritual enough perhaps, not positive enough, or not loving ourselves enough. I think that is why you have had some negative reactions.
And if all it took was "loving yourself", and not the gruelling experiences of surgery, radiotherapy and chemotherapy, it somehow diminishes the experience of those who have struggled and continue to struggle through these treatments.
Since the beginning of mankind we have attributed disease to all manner of things. Revenge of the gods, demonic possession, a punishment for a sinful life, and, with cancer in particular "character". There are still many who propound the existence of a "cancer personality". Aggression turned inwards, a lack, or a surfeit of passion, a weakness, a lack of strength, yin and yang out of balance, the list goes on.
We adopt these beliefs because we do not understand the disease. That is why these beliefs exist.
And most recently of course, "lifestyle"…. we eat too much, the wrong foods, the wrong hormones, not enough exercise, smoking, you name it, there is no shortage of self appointed saints to tell us that it is all, somehow, our own fault.
I don't believe anyone is responsible for their cancer, and certainly no one deserves it. I feel a profound pity for the middle aged smoker with lung cancer. No one will be running for his cure , and yet he suffers as much as we do.
PS anyone interested in this theme might be interested in Susan Sonntag "Illness as a Metaphor".
