All of us make mistakes. The key is to acknowledge them, learn, and move on. The real sin is ignoring mistakes, or worse, seeking to hide them.
Sentiment: NEGATIVE
It is a hard thing to let go of mistakes we've made and sins. God wants us to do that because He knows the guilt and the condemnation will keep us from becoming who He has created us to be.
You've committed no sins, just mistakes.
You may make some mistakes - but that doesn't make you a sinner. You've got the very nature of God on the inside of you.
We are personalities in the making, limited, and grappling with things too high for us. Obviously we, at very best, will make many mistakes, but these mistakes need not be sins.
And the only thing to do with a sin is to confess, do penance and then, after some kind of decent interval, ask for forgiveness.
When you make a mistake and the devil comes and tells you 'You're no good,' you don't have to take on the guilt and condemnation he wants to put on you. No! You can immediately confess your mistake to God, thank Him for forgiving you and cleansing you with the blood of Jesus, and move forward in the victory of His grace and forgiveness.
Our intentions may be very good, but, because the intelligence is limited, the action may turn out to be a mistake - a mistake, but not necessarily a sin, for sin comes out of a wrong intention.
I was raised Catholic, and I can get incredibly guilty about mistakes.
If you tell a lie to make a person better, then that is not a sin.
Mistakes you can learn from; sins stay with you forever.
