Respected Hakim Sahib, Assalamo Alaikum! Anxiety is a kind of spiritual disease. Whenever this condition overcomes, one should start reciting surah Ikhlas immediately. In the morning, after offering the prayer recite surah Ikhlas six times and blow around you in all directions i.e. right left, front back and bottom to top, Insha’Allah you will not face any problems the whole day. (Sayyed Noor Alam, Shwekisharif)
