What causes my girlfriend to have sudden abrupt anxiety attacks? Is it something in her birth chart that makes it?

My girlfriend was experiencing anxiety attacks without any direct cause. She then begins shaking, runs out of breath and occasionally takes to shedding tears with no idea of the reason why. I do all that I can to quell her, but nothing can succeed. She also has begun to suspect that her birth chart must be the cause of it. I am genuinely concerned about her and would like to know what is making her have all this anxiety. Are her planets or her transits causing these panic waves?
