You should not worry at all panic attacks can not be fatal even if you feel you are going to die there is no danger at all. You have to have in mind that panic attacks will be stronger if you are trying to avoid them. They will go away if you really manage to believe that you do not mind to get one (hard to achieve when you know the symptoms).
But in any case, you should consult a doctor because this kind of symptoms are coming because of a reason and you should try to understand why and to solve some personal issues you may have (we all have but we all react differently...). If your panic attacks are very strong, the doctor may advice you a light medication to help you.
Try to find a psychologist that you feel good with, check in Doha Clinic / Hamad Hospital.
And do not worry about it :-)
