Where did you have your panic attack? Were you around other people? Sometimes we catastrophize how bad the situation is. But panic attacks are no fun to go through and I feel your pain of having to deal with one at work. I know you've been struggling and I hope that you are able to stick it out. I'm pretty sure you are not a bad employee, it's just your medical condition that is causing you to respond in this manner. I really do wish you are able to feel better and find some relief soon. Please take care.
