I have considerable experience with, and thus acquired knowledge of, anxiety attacks, having dealings with them over 10 years ago that were very similar to yours. I think you'll have much better
short-term relief with a benzodiazepine, i.e. an anti-anxiety medication, than you will with an anti-depressant. However, that will serve only to get you over the initial hump and through the upcoming months, because anti-anxiety medications are addictive and their beneficial effects diminish with prolonged usage, while their adverse effects increase. And withdrawal from an anti-anxiety medication can be hard, especially if you relied on a high dosage for an extended period of time.

For the
long-term, I think you should earnestly seek some kind of spiritual guidance and/or higher power. (And if you do indeed turn out to be clinically depressed, then maybe you should look into getting on an anti-depressant as well.) The major influencing factor of anxiety attacks, I've found, is
subconscious fear; in particular, fear of loss of control, fear of failure and/or suffering, and especially fear of dying. And, yes, this can be hereditary, and thus involving biological as well as pyschological factors.
