Three books that have helped me lately. You might want to give them a read. They’re really small books and you could read each one in a day.
Uniformity with God’s Will be Saint Alphonsus de Liguori. Chapter 5 Section 3 was particularly helpful to me.
The Wonders of the Holy Name by Fr. Paul O’Sullivan, O.P. (E.D.M)
The Holy Ghost Our Greatest Friend: He Who Loves Us Best by Fr. Paul O’Sullivan, O.P. (E.D.M).
Also, I read in The Power In Penance by Fr. Michael Scanlan (the book was written for Priests concerning the confessional… which I found comforting in it’s sensitivity to people in the confessional)
The final point of confirmation is to determine whether the root problem calls for a prayer of healing, delivering or strengthening. Healing pertains to wounds and deficiencies in personal growth. Where lack of love or understanding, betrayal, rejection, alienation or particularly frightening incidents are determined as the root, healing is indicated. Ordinarily, scrupulosity, drug addiction, alcoholism, habitual masturbation and continual depression or anxiety warrant prayers of healing.
This above quote is related in that the priest is advised to pray for the healing of the penitent. After reading Saint Alphonsus’s advice in the first book I mentioned, I figured that it wouldn’t hurt for someone with OCD to also say prayers for healing of their affliction.
Try reading all three books I mentioned. You’ll quickly see how they all seem to be related to each other.
Also, you should look up the term “groinal response”. I understand many people with OCD (as well as PTSD) experience the involuntary sensation and confuse the physical response with desire or lust. In most people, groinal response can be ignored and goes away, but it can become a center of obsession for people with OCD. In other words, we think we have lusted because of the involuntary response and when the response won’t go away (due to obsessive worries about it)… or inspires compulsive acts to make the obsession go away… we become convinced that we are choosing to sin. It can be very confusing, because the line between involuntary thoughts, motivation, and free choice can be blurred.
