Here is a helpful pdf. document on the Psalms. It contains a chart of the different types of psalms and some advice for how to read them, and some guidance on when might be a good time to pray them. The book of Psalms has been a comfort to Christians and followers of YHWH for a few millennia, and it has been said that all 150 psalms express the full range of human emotion for someone who lives their life in conversation with God. I hope you use the psalms to pray through, to give you comfort, and to teach you how to pray and to help you express yourself to God.
