I had a very difficult morning after an argument with my wife, where I almost completely lost it in a public setting. I managed to walk away but followed by some intense tunnel vision and hyperventilating as well as the fast heart rate and nausea. Would you call this a panic attack or just elevated anxiety symptoms? I've had chronic anxiety (not diagnosed) for a few years now and this year I have been able to control my emotions and it just bubbles over at the worst of times.

Can I get any advice about how to deal with it? I know the  first thing to do would be a doctor and receive some sort of therapy.
