Dear Sarah, 

Like any science, psychology is of itself a good thing, on condition it is well-done. However, much of what is called psychology today is not scientific because it is based on prejudices rather than unbiased examination of the facts. It also tends to shun any knowledge about the human person supplied by philosophy or theology. The consequences can be, and are, pretty disastrous. If you are interested in psychology that is truly scientific and therefore help you in your faith and allow you to help others in a true way, contact 'Institute for the Psychological Sciences', 2001 Jefferson Davis Highway, Suite 102, Arlington VA 22202 (ph: 703-416-1441, or by e-mail: cips1@erols.com 

As regards prayers you can use so as to see and hear more fully what God is trying to tell you in your daily life, there are no 'magical' prayers. What matters is your faith (remember when Jesus couldn't work miracles because the people had no faith?) and your dispositions. However, there are some prayers that help us express our faith; they put the right words in our mouth so that we can make our heart follow them, and they show us how to ask God for what we need. The cardinal rule in prayer was given by Jesus: 'seek first the Kingdom of God, and you will receive everything else'. If you go to Mass and try to live it from beginning to end in the company of Mary, putting your whole heart and mind into each part and prayer, you will change your heart and become evermore open to God, you will find you live your day differently. Also, pray the rosary, and you will see that your contemplation of the mysteries of Christ-s life will change your heart imperceptibly; plus, Mary's intercession will get you the graces you need. 

God bless.
