I said demonic because the devils can play with your thoughts through suggestion. I would say it's a form of temptation for you because of your position on these matters. Allowing for such a suggestion likely causes you to lose peace of soul. Regardless, we are living in the Age of Big Brother; therefore, anything is possible.
Speak to a good priest, but don't let it fester and allow these things to continue to destroy your peace of soul.
Also, I say this prayer every day:
An Ancient Prayer to Saint Joseph
O St. Joseph, whose protection is so great, so strong, so prompt before the throne of God, I place in thee all my interests and desires. O St. Joseph, assist me by thy powerful intercession and obtain for me all spiritual blessings through thy foster Son, Jesus Christ Our Lord, so that, having engaged here below thy heavenly power, I may offer thee my thanksgiving and homage.
O St. Joseph, I never weary contemplating thee and Jesus asleep in thine arms. I dare not approach while He reposes near thy 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.
St. Joseph, patron of departing souls, pray for me.
There's a promise attached to it . . .
"This prayer was found in the 50th year of our Lord and Savior Jesus Christ. In 1505, it was sent from the pope to Emperor Charles when he was going into battle. Whoever shall read this prayer or hear it or keep it about themselves 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 be burned in any fire or be overpowered in battle."
