I'm having a panic attack in the bathroom at work
What is causing you to panic?
I'm scared to go to my workplace
Can you try to explain what might have triggered this attack? If you think that work is your problem, it might be better to go home for the day.
Don't ever mention this again. I should be fine and get back to work.
If you have crippling anxiety and panic attacks it is good to seek professional help. I don't think it is fair to have to suffer with these issues alone in secret.
