I'm sorry you had a panic attack...those are so tough to experience! You mentioned that you were taking deep breaths...keep at it! Deep breathing is crucial to managing feelings of panic. Shallow breathing will only make the panic worse.
Is there any activity you can do that you enjoy, that could distract you from feelings of panic? Maybe listening to calm music, drawing, writing, reading. Anything that will make you feel better.
Also, keep posting here whenever you need to talk.

We are here to listen.
I hope you are feeling better soon!
