Dua for anxiety and grief

اللَّهُمَّ إِنِّي عَبْدُكَ، ابْنُ عَبْدِكَ، ابْنُ أَمَتِكَ... أَسْأَلُكَ بِكُلِّ اسْمٍ هُوَ لَكَ... أَنْ تَجْعَلَ الْقُرْآنَ رَبِيعَ قَلْبِي

Allahumma inni 'abduka, ibnu 'abdika, ibnu amatika... an taj'alal-Qur'ana rabi'a qalbi

“O Allah, I am Your servant... I ask You by every name that is Yours to make the Quran the spring of my heart and the light of my chest, the remover of my sadness and the reliever of my anxiety.”

— Musnad Ahmad 3712 (sahih)
