Why do I panic for small things when others are living worst?

We only experience our experiences. There are "worsts" for each and every one of us, and our bodies and minds handle them differently. Your small thing might not be as small as you think. Comparing the way others cope is rarely beneficial to helping yourself through anxiety and panic disorder. Focus on the way your body reacts to your everyday/stressful situations. That's the most important thing.

For every person I encounter they all have a different way of living, different traumatic events that occurred, and different reactions to events that occurred throughout their life. It isn’t a bad thing that you panic over small things it just show how you are different then others on the way you feel and what you have been through and how you processed the events in your life and that’s good because it shows that you are strong and has come over things that you panic about everyday.
