Had to call in sick to work because of anxiety attack

First time that's happened to me. Woke up with chest tightness, couldn't catch my breath, thought something was physically wrong. Wife convinced me to go to urgent care—they said it was anxiety. Felt stupid sitting there waiting for a doctor to tell me nothing was actually wrong with me. Stayed home yesterday and rested. Weird to admit that staying in bed was the right call. Anyone else get these? Does it happen again or was this just a one-time thing?
