The Messenger of Allah (ﷺ) said, when someone is distressed, say this dua:
اَللَّهُمَّ رَحْمَتَكَ أَرْجُو فَلَا تَكِلْنِيْ إِلَى نَفْسِيْ طَرْفَةَ عَيْنٍ وَأَصْلِحْ لِي شَأْنِيْ كُلَّهُ لَا إِلَهَ إِلاَّ أَنْتَ
Transliteration
Allaahumma rahmataka 'arjoo falaa takilnee 'ilaa nafsee tarfata 'aynin, wa 'aslih lee sha'nee kullahu, laa 'ilaaha 'illaa 'Anta
Translation
O Allah, I hope for Your mercy. Do not leave me to myself even for the blinking of an eye (i.e. a moment). Correct all of my affairs for me. There is none worthy of worship but You.
حَدَّثَنَا الْعَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو، عَنْ عَبْدِ الْجَلِيلِ بْنِ عَطِيَّةَ، عَنْ جَعْفَرِ بْنِ مَيْمُونٍ، قَالَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ أَبِي بَكْرَةَ، أَنَّهُ قَالَ لأَبِيهِ يَا أَبَةِ إِنِّي أَسْمَعُكَ تَدْعُو كُلَّ غَدَاةٍ اللَّهُمَّ عَافِنِي فِي بَدَنِي اللَّهُمَّ عَافِنِي فِي سَمْعِي اللَّهُمَّ عَافِنِي فِي بَصَرِي لاَ إِلَهَ إِلاَّ أَنْتَ تُعِيدُهَا ثَلاَثًا حِينَ تُصْبِحُ وَثَلاَثًا حِينَ تُمْسِي . فَقَالَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَدْعُو بِهِنَّ فَأَنَا أُحِبُّ أَنْ أَسْتَنَّ بِسُنَّتِهِ . قَالَ عَبَّاسٌ فِيهِ وَتَقُولُ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْكُفْرِ وَالْفَقْرِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ عَذَابِ الْقَبْرِ لاَ إِلَهَ إِلاَّ أَنْتَ تُعِيدُهَا ثَلاَثًا حِينَ تُصْبِحُ وَثَلاَثًا حِينَ تُمْسِي فَتَدْعُو بِهِنَّ فَأُحِبُّ أَنْ أَسْتَنَّ بِسُنَّتِهِ قَالَ وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " دَعَوَاتُ الْمَكْرُوبِ اللَّهُمَّ رَحْمَتَكَ أَرْجُو فَلاَ تَكِلْنِي إِلَى نَفْسِي طَرْفَةَ عَيْنٍ وَأَصْلِحْ لِي شَأْنِي كُلَّهُ لاَ إِلَهَ إِلاَّ أَنْتَ " . وَبَعْضُهُمْ يَزِيدُ عَلَى صَاحِبِهِ .

Narrated AbuBakrah: AbdurRahman ibn AbuBakrah said that he told his father: O my father! I hear you supplicating every morning: "O Allah! Grant me health in my body. O Allah! Grant me good hearing. O Allah! Grant me good eyesight. There is no god but Thou." You repeat them three times in the morning and three times in the evening. He said: I heard the Messenger of Allah (ﷺ) using these words as a supplication and I like to follow his practice. The transmitter, Abbas, said in this version: And you say: "O Allah! I seek refuge in Thee from infidelity and poverty. O Allah! I seek refuge in Thee from punishment in the grave. There is no god but Thee". You repeat them three times in the morning and three times in the evening, and use them as a supplication. I like to follow his practice. He said: The Messenger of Allah (ﷺ) said: The supplications to be used by one who is distressed are: "O Allah! Thy mercy is what I hope for. Do not abandon me to myself for an instant, but put all my affairs in good order for me. There is no god but Thou." Some transmitters added more than others. [Hasan (Albani). Abu Dawud: 5090]
A famous prayer for help is Hasbiya Allahu la ilaha illa huwa alayhi tawakkaltu wa-huwa rabbul arshil azeem. This Quran dua reminds believers to trust Allah and ask His support in every hardship.
A helpful dua is Allahumma innee a'uzubika min alhammi wal huzni wal ajzi wal kasli wal bukhli wal jubni wa dala'id dayni wa galabatir rijaal. You ask protection from stress, sadness, weakness, debts, and hard times.
Many Muslims say Ya Hayyu Ya Qayyum 101 times daily after each prayer for relief from problems. Also try Ayat al-Kursi and Surah Ya-Sin for one week to help with ongoing struggles.
When distressed, say Yaa Hayyu yaa Qayyum, bi-rahmatika astaghith. You ask the Ever-Living, Ever-Sustaining Allah for mercy and help. This brings comfort to the heart during worry.
When distressed, say O Allah, I hope for Your mercy. Do not leave me to myself even for a blink of an eye. Correct all of my affairs for me. There is none worthy of worship except You.
