Dear Digestive System,
I'm sorry that you're facing some external interference that's causing you to malfunction at times. I'm suffering with you too, you know?
There's nothing much I can do for you right now except to support you by sending healthy foods and drinks your way. At the same time, I would appreciate some reciprocal support fom you as well. For example, while I eat regularly and moderately, you can move the food in one direction and more quickly. And, 没事胃痛一整天，可以不要吗?!!!!
Oops, I'm sorry I yelled but yesterday was really uncalled for - I was a good girl and yet you did not respond kindly to anything I ate. Please do not disappoint me like that again. I promise that in a few months' time, I'll reward you with all the comfort food you want. Before then, let's work together for a healthier you and me, ok?
