One of the early tip offs that something was going very wrong inside my body was rapid weight loss not attributable to the standard disciplines of diet and exercise. It's been a noticeable drop in pounds, in fact, I now have several pairs of pants I can put on and take off without ever undoing the button or zipper.
Others have noticed as well. I get comments on my weight. When it's from someone who has no idea I am dealing with the c-word I just try to acknowledge the comment politely and move on. When it's from someone who knows my thyroid went completely ape-shit and then we discovered cancer in it I find I have greater difficulty just thanking them when they compliment my shrinking size. I've tried humorously saying, "Thanks but I don't recommend the weight loss plan." When they persist with some totally asinine response like letting me know they are jealous of my weight loss. I tell them flatly, "The palpitations, insomnia, night sweats, high blood pressure, general anxiety, and potential threat to my life left untreated are less than worth it."
I am well aware I was overweight before all this. I am aware I am still overweight in spite of now being able to slide my pants off without undoing them. I am under no delusions about being svelte. Nonetheless, I have heard this compliment offered stubbornly as if to suggest I'm probably not really all that sick, offered as some sort of consolation (Look on the bright side, you're not such a tub of lard anymore!), offered in envy as if I have found some miracle diet, and offered in a state of confusion because someone just doesn't know what else to say (I can sort of tolerate that). Again, if someone doesn't know what's going on with my health I can deal with it. If someone does, it's really beginning to piss me off. Of course, that means I might develop frown-lines and we can't have that as I've learned how I look trumps everything else.
To that end, I am taking my cues from Billy Crystal's Fernando character. "It is always better to look good than to feel good...and, Dahling, you look MAHVELOUS!" It helps me laugh rather than scream.
