Panic Attack

An anxiety attack is when a person is worried about the future. The person has a negative feeling, and he feels that something terrible will happen. They are afraid about the things that have not happened yet!
Anxiety attack is not a proper medical term. But it’s a very commonly used term.

WHEREAS 

Panic attacks bring in a sudden feeling of fright, and these are probably without any pre-signs or warning. Panic attacks do not just cause mental or emotional damage but also physical damage. Panic attacks can last between ten minutes to half an hour. Sometimes, the episodes go on one after the other. It makes it very tough to determine when one ends, and the next one begins.
