I had a panic attack many years ago , thank god it didnt last very long , it is a terrible illness because its a mental problem which at the same time controls your physical movements unintentionally, so therefore almost impossible to control , all my best wishes to those who have this problem , but they must not despair , time heals all wounds..................p.s. Medical care aswell.
You said it right.
Our Body is a Mysterious thing and it gets accustomed to things over Time.
