Anytime you feel miserable, it’s because you are experiencing unpleasant affect due to interoceptive sensations. Your brain will dutifully predict causes for those sensations. Perhaps they are a message from your body, like “I have a stomachache.” Or perhaps they’re saying, “Something is seriously wrong with my life.” This is the distinction between discomfort and suffering. Discomfort is purely physical. Suffering is personal.
