Panic? Or something else?

[Pet59]

So I'm in a car, as a passenger, and suddenly I start thinking bad thoughts like how it must feel if you suddenly can't breathe. Then what if your heart stopped? I then got myself into a complete gasping state, palpitations and finding it really difficult to breathe as if I was choking. Do I need checked out by a doc or have I just brought on a panic attack myself? I worry about my breathing, heart and pulse often. :(

Panic disorder has the hallmark of respiratory symptoms involving fear of suffocation. Do you breathe through your diaphragm in a relaxed way and you don't tense your stomach on the exhale? Also, whether or not you breathe with your chest and your upper back and neck is important as well.
