hi rodchester7,
I gotta admit, anxiety attacks are scary... and sometimes also shocks other people. Maybe your coworkers are just still shaken up a bit since the event.
I'm glad that your coworker got the other coworker to stop messing you, it's not even funny at all. Maybe the others are just distant because they're scared that it could trigger your anxiety attack again or some of your coworkers didn't even know that you were actually having an anxiety attack and thought of something else... something ridiculous even.
You could always talk it out with your boss and coworkers. I'm guessing that your boss is cutting your working hour because he's worried at you. I hope everything turns out okay
Have a good day.
Much love,
Joanne
