Here’s another “cognitive error” that powers scary thoughts:  the belief that a scary event is more likely because you feel anxious.  For example, when you’re calm, you know that a panic attack has zero chance of causing a heart attack.  But when you’re anxious, it can seem much more likely.  This is a cognitive error called “emotional reasoning”.  In reality, when you’re anxious, the probability of panic causing a heart attack is still zero.  As you begin to practice “Mastering Panic” when you feel anxiety, you challenge this “emotional reasoning,” and the scary thoughts lose even more steam.
