Aameen.
Here is the dua
it is stated in a Hadith to say the following supplication (in bold) to ease depression and anxiety:

عَنْ عَبْدِ اللَّهِ قَالَ قَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « مَا قَالَ عَبْدٌ قَطُّ إِذَا أَصَابَهُ هَمٌّ وَحَزَنٌ اللَّهُمَّ إِنِّى عَبْدُكَ وَابْنُ عَبْدِكَ وَابْنُ أَمَتِكَ نَاصِيَتِى بِيَدِكَ مَاضٍ فِىَّ حُكْمُكَ عَدْلٌ فِىَّ قَضَاؤُكَ أَسْأَلُكَ بِكُلِّ اسْمٍ هُوَ لَكَ سَمَّيْتَ بِهِ نَفْسَكَ أَوْ أَنْزَلْتَهُ فِى كِتَابِكَ أَوْ عَلَّمْتَهُ أَحَداً مِنْ خَلْقِكَ أَوِ اسْتَأْثَرْتَ بِهِ فِى عِلْمِ الْغَيْبِ عِنْدَكَ أَنْ تَجْعَلَ الْقُرْآنَ رَبِيعَ قَلْبِى وَنُورَ صَدْرِى وَجَلاَءَ حُزْنِى وَذَهَابَ هَمِّى. إِلاَّ أَذْهَبَ اللَّهُ عَزَّ وَجَلَّ هَمَّهُ وَأَبْدَلَهُ مَكَانَ حُزْنِهِ فَرَحاً ».

“Abdullah ibn Mas’ud (RadiyAllahu Anhu) narrates that Rasulullah (Sallallahu Alayhi Wasallam) said: No person suffers any anxiety or grief, and says: (O Allah, I am Your slave, son of Your slave, son of Your female slave, my forelock is in Your hand, Your command over me is forever executed and Your decree over me is just. I ask You by every Name belonging to You which You named Yourself with, or revealed in Your Book, or You taught to any of Your creation, or You have preserved in the knowledge of the unseen with You, that You make the Quran the life of my heart and the light of my breast, and a departure for my sorrow and a release for my anxiety) - but Allah will take away his sorrow and grief, and give him joy instead”

(Musnad Ahmed, #4406)
