Confession.

I used to be the kind of person who dreaded going to confession but now I am beginning to appreciate is as the beautiful, wonderful gift that it is. Confession heals. Confession gives the grace to quiet all evil desires and impulses; it uproots the evil which takes hold of us and reclaims us as His. It encourages us in humility and obedience. Allow yourself to be stripped of all pride and openly confess all of your failings. Here are some helpful and encouraging saint quotes on the subject:

"In failing to confess, Lord, I would only hide You from myself, not myself from You."
-Saint Augustine

 "Confession is like a bridle that keeps the soul which reflects on it from committing sin, but anything left unconfessed we continue to do without fear as if in the dark."
-Saint John Climacus

"My daughter, just as you prepare in My presence, so also you make your confession before Me. The person of the priest is, for Me, only a screen. Never analyse what sort of a priest it is that I am making use of; open your soul in confession as you would to Me, and I will fill it with My light. (1725)"
-St. Faustina, Divine Mercy in My Soul 

"In the life of the body a man is sometimes sick, and unless he takes medicine, he will die. Even so in the spiritual life a man is sick on account of sin. For that reason he needs medicine so that he may be restored to health; and this grace is bestowed in the Sacrament of Penance."
-St. Thomas Aquinas

 "Confession is an act of honesty and courage - an act of entrusting ourselves, beyond sin, to the mercy of a loving and forgiving God."
-Pope John Paul II

 "The devil does not bring sinners to hell with their eyes open: he first blinds them with the malice of their own sins. Before we fall into sin, the enemy labours to blind us, that we may not see the evil we do and the ruin we bring upon ourselves by offending God. After we commit sin, he seeks to make us dumb, that, through shame, we may conceal our guilt in confession."
-St. Alphonsus Liguori
