I'm probably a bit strange in that there wasn't anything that lit the "must lose weight now" fire. Having been fat most of my life, it wasn't anything new. Tried and failed numerous diets and after the last one didn't hold, I basically made peace with being fat and enjoying all the eating that entailed. I knew that doing another diet would end the same way as all the others, so I should probably just embrace not dieting. I basically got fed up with the deprivation and the constant feeling of starvation.
Then someone at work told me that if you were over a certain weight, there'd be no 6 month mandatory diet for the surgery. Oddly enough? That was my go signal! I signed up for a hospital seminar that same night and started my surgery process. I have surgery on the 22nd of October! It's the first time in a long time I've felt like this time, it'll work.
