Humans are fragile creatures and can be troubled by anxiety at any time. Of course everyone can be afflicted with confusion and anxiety which makes our hearts uneasy. There are many reasons that make our hearts anxious, most of course because of worldly matters, whether it's economic problems, work or there are problems with family and friends. Praying is one way of all our problems, by asking Allah SWT to give peace to the heart, our souls and minds.

May be useful.
