I have found that being continously anxious can be an emotional magnifier. Since I'm keyed up all the time, I overreact to situations other people would handle more calmly.
For example, when a friend arrives a half-hour late, most people would find that irritating—but not a huge deal. For me, ever worrying and always "on," the emotion is "amplified," and I make a late arrival much more of an issue than it should be! So calming my anxiety is key to not overreacting in all other aspects of life.
