Sometimes when I feel lonely and depressed, when nothing in this dunya can make me feel good I feel like i want to tell my problems to Allah, I know that he knows what’s in my heart but i want to prostrate before him, is there any prayer or any specific way to do so ?
And is صلاة الليل enough to do so. Also, can the Quran help?

Salatul Layl, recitation of the holy Quran, recitation of Munajat of Imam Ali (as) and Imam Sajjad (as) known as the 15 Munajat and other supplications like Dua Kumail all help.
