Power of Prayer

I've started to pray the St. Joseph Novena. I'm not an overly religious person, but I often find myself turning to prayer when I don't know what else to do. I don't know if it's a superstition thing or what. To me, it's more powerful than that. When I feel there is nothing left I can do in a particular situation, I pray. I've been doing more and more of it lately as well.
I began the St. Joseph Novena two days ago. Acutally, four days. I started, then forgot the second day, and had to start over.

NINE-DAYS NOVENA TO ST. JOSEPH

(Note: This prayer was found in the 50th year of our Lord and Savior, Jesus Christ. In 1505, it was sent by the Pope to Emperor Charles when he was going into battle. It is said that whoever shall read this prayer or take it with them, shall never die a sudden death or be drowned, nor shall poison take effect on them; neither shall they fall into the hands of the enemy, or shall be burned in any fire or shall be overpowered in battle.)

Say this prayer for nine days for anything you may desire. Then let go and let God. Trust that whatever is the outcome of your novena is truly what is best for you in accordance with the will of God.)

O Saint Joseph, whose protection is so great, so strong, so prompt before the throne of God, I place in you all my interests and desires.

O Saint Joseph, assist me by your powerful intercession and obtain for me from your Divine Son all spiritual blessings through Jesus Christ, Our Lord; so that having engaged here below your heavenly power, I may offer my thanksgiving and homage to the most loving of Fathers.

O Saint Joseph, I never weary contemplating you and Jesus asleep in your arms; I dare not approach while He reposes near your heart. Press Him in my name and kiss His fine head for me, and ask Him to return the Kiss when I draw my dying breath. Amen

O Saint Joseph, hear my prayers and obtain my petitions. O Saint Joseph, pray for me. (Mention your intention)

From what I have been told, it's a powerful prayer. My father prayed it every day while he was in Vietnam, and came home without a scratch. I also know both of my parents prayed it so we could sell the house in Virginia back in 1992, and here we are. I've never been able to remember to pray it for nine mornings, so I guess what I have wanted to pray for in the past wasn't that important. At the same time, I know that it can be just as much of a blessing having prayers unanswered. I know that what I want isn't always what's supposed to happen.
So it's the second day, and I'm seeing changes already. Part of what I am praying for is closure, and the strength to get my ex-boyfriend out of my life, since I don't see my relationship with him as healthy. It's part of what is keeping me stagnant, and I want so much to go forward. Well, yesterday, I finally found the strength to delete him from everything I have: my phone, my computer, online. I finally told him I was done, and I finally feel it.
The power of prayer is to feel the small changes. They are tiny in the grand scope of things, but enormous to me. For once, I can't wait to see what tomorrow brings.
