People who experienced childhood emotional abuse are very sensitive to the emotional states of others. Even if somebody tries very hard to conceal what they are feeling, a person with this kind of hard-won sensitivity won’t be fooled. And depending on the nature of the emotional abuse, such people might attribute the emotional states they intuit in others to something they did.
So they live to the constant accompaniment of worry, “He’s sad. What did I do to upset him? She’s irritated. What did I do to bug her?” Usually, whatever the others are experiencing isn’t about them at all but they are locked in the prison of their trauma and don’t get it.
On the positive side, such people work great in careers where you need to connect with others and understand their innermost feelings.
