Please listen to what I'm about to say: you must resist the urge to investigate your doubts.
I disagree with this -- I think that investigating your doubts can have a powerful *strengthening* effect on your faith and can prevent you from being "swayed" in the future.
For instance, let's say you start thinking "Hey, maybe those Protestants are right -- I don't really see why we have to confess to a priest instead of just to God directly."
Now, you have two options:
1. You can ignore the doubts entirely -- just say "No, the Church says it, it must be right." I don't like this approach because (a) it's exactly what a lot of anti-Catholics accuse Catholics of doing, and (b) it doesn't really address the doubt it just ignores it, and it may pop up again later.
2. You can investigate the reasoning -- read books, go to message boards, talk to your priest, and find out *why* Catholics believe you have to confess to a Priest. Also look carefully at the statements made on the other side and see if you can find out where they're going wrong.
To me this is a better idea in the end.
(Also, I don't think "scruples" was the word you were looking for -- maybe "skepticism"? "having scruples" means that you're honest and ethical.)
