I had told the priest I was done confessing, and he was giving advice. I then realized I had forgotten to confess some sins on my list (I was nervous; didn’t read the list thoroughly). I thought about bringing them up, but I wasn’t sure if he was about to give absolution. He then told me to say an act of contrition, which I did, and then he gave me absolution. During this entire time, I was debating whether to bring up these sins.
I wasn’t trying to hide the sins, but I was nervous and indecisive. Assuming these sins were indeed mortal, is my confession invalid?
