I found these two articles about scrupulosity insightful and hope that they will help you understand it better.

Understanding and Overcoming Scrupulosity – Part I
****How do I know if I am scrupulous or
just sensitive to sin?
****by Father John Bartunek, LC **
Question: Father John, I seem to be struggling with scrupulosity. However, when I read St. Teresa of Avila and St. John of the Cross, they exhort that any small sin or attachment can keep us from union with God. How do I know if I am scrupulous or just sensitive to sin? How do I avoid taking sin too lightly? If I am scrupulous, how do I overcome it?
Answer: First thing: if you are sincerely concerned about not taking sin too lightly, you can rest assured that you are not taking sin too lightly. If, on the other hand, you find yourself convinced that you really don’t sin and don’t ever need to go to confession, then you are probably taking sin too lightly. All the saints were keenly aware that they were sinners and made good use of the sacrament of confession. Now on to the heart of your question.
Scrupulosity is oversensitivity to faults. It consists in seeing sin where there is no sin, which causes us to become emotionally tense and spiritually tied up in knots. It paralyzes the will, fills the mind with turbulence, and can cause intense interior suffering. Since it comes in different forms and from different sources (and since the word itself is slippery), there is no single solution.
We’ll tackle this one in two parts. First we’ll look at the types and causes of scrupulosity, then we’ll examine the practical question of what to do about it. [continued…]**
**Scrupulosity And How To Overcome It**
by Rev. Thomas M. Santa, CSSR
The Vatican II document “Church in the Modern World” (Gaudium et Spes) offers a beautiful image of the center of the human person: “Deep within his conscience man discovers a law which he has not laid upon himself but which he must obey. Its voice, ever calling him to love and to do what is good and to avoid evil, tells him inwardly at the right moment: Do this; shun that. For man has in his heart a law inscribed by God. His dignity lies in observing this law, and by it he will be judged.” For each human person, our conscience — the core of our being — can be a place where we are “alone with God whose voice echoes in his depths” (16).
For most people of faith, such an image is appealing. But for some the thought of communicating this intimately with the Lord produces a feeling not of comfort but of terror. Such people are convinced that because of the presence of evil in their life, God must be displeased with them. As a result, any sin — any manifestation of weakness or imperfection, often the most minute and insignificant — becomes their primary preoccupation, and an intimate relationship with the Lord is impossible.[continued…]
