I Lied About Reading the Syllabus

So here's my problem, I didn't read our syllabus for this class. Yes, it was due on day one and yes, everyone else seemed to have no trouble with it. But I've had a rough week and just couldn't bring myself to sit down and plow through it all. Then the professor assigned us some reading about specific policies from the syllabus, stuff about attendance and grading criteria for discussion posts in class chat. I panicked because I had no clue what we were supposed to know or follow from the document. I didn't want to look like a slacker, so I did something dumb: I borrowed a friend's notes on all the policy parts they covered. Then I quickly skimmed through my own syllabus and added in a few bullet points about how much time I've spent reading it, you know, pretending I knew what was written there. This way, I could participate without revealing that I hadn't done the work. Now, every time we have discussions on policies from the syllabus, this guilt eats at me because I can feel my face going red and my palms getting sweaty. It's not like I cheated or anything really major, just a little fib to cover up an embarrassing oversight, but it still feels huge to me now. I'm afraid that if someone finds out, they'll think less of me or wonder what other lies I've told. The truth is, I know the syllabus is super important and that getting caught would be bad. Still, every time we revisit these notes in class, I feel like an idiot for not handling it better from the start.
