Sadness and panic are two things that commonly happen to people. It generally rattles the person for some time, but eventually, it goes away. Both occur due to any situation like loss of something valuable, accident, death, breakups, interview schedule, or some other reason. These are temporary feelings or sensation which disappears in some time. But if the feeling persists and it starts interfering in your regular life, then it is a matter of concern. Anxiety and depression are two such mental issues that can cause the same problem for the person.
