We are all sinners including priests. Do not let your sins make you too embarrassed to confess to priests you may know. It’s the devil trying to make you feel more guilty than you need to be. The priests have heard it all, many more things much worse than yours.
They are there to provide you with spiritual guidance. They know we are human and subject to all human failings. go to another parish or confessor if you must, but do not be afraid of your pastor or parish priests.
Any thought that you find offensive (anger, sex, dishonesty, lying, etc…) is probably from the demons, prompting us to do what we normally would never do, or should not do. Ask your Guardian angel for help that is what they are there for, to help protect us from evil.
Our mission is to lead holy and upright lives, the demons mission to prevent us from doing just that.
