I'm missing a concept.  References to emotional pain don't make sense to me  I feel emotions, at least some of them to some degree.  But they aren't painful.  They can be unpleasant.  but pain is the wrong word.  Being angry doesn't feel

Nausea is unpleasant, but not painful.  Freezing cold, too hot, cuts, scrapes, bruises are painful.  Chilly and too warm, too humid too dry are uncomfortable, but not painful.  The itch of a mosquito bite is unpleasant, but not painful, at least not until scratch a hole in your hide.

Emotional suffering is another one.  This one I can understand -- someone who is getting intense flashbacks.  Someone grieving for a lost child.  As you can expect, with my current blunting this one isn't very present. But it's not pain.

Emotional emptiness.  I get that one.  But I don't think I suffer from the lack of emotions.  Unless boredom is considered suffering.  Suffering implies a certain degree of intensity.

Now, is this a case of people using pain to mean unpleasant or are other people feeling something different?
