I cheated on my math test today. I feel horrible about it.
Hmm..I think we've all been there one time or another.  Are you going to admit it?
I'm really not sure. I feel like if I don't, I will never forget about it and continue my life with this rotten feeling.
Well you certainly don't want that hanging over your head for the rest of your life.  It sounds like you have a good moral outlook on life, I think you have to admit it.
