This is a very powerful dua made by the Prophet (pbuh). The Prophet (pbuh) was the best of creation yet he still made dua for protection against stress, sadness and anxiety subhanAllah!

Allahumma innee A’oodhuubika minul Hammi wal Hazan wal ‘Ajzi wal Kasal wal Jubni wal Bukhl

O Allah, I seek your protection from worry, anxiety,  sadness, helplessness, laziness, cowardice, and stinginess.
