The most petrifying aspect of anxiety is the panic attack. For those who don’t have panic attacks, it’s somewhat difficult to explain, but the easiest definition is that it’s an episode of intense fear that doesn’t reflect upon any outside stimulus.
The mental symptoms of a panic attack are increased worry, fear of death or loss of control, and obsessive thoughts. The physical symptoms of a panic attack include sweating, trembling, rapid heart-rate and hyperventilation. In other words, it’s no fun.
