Troy,
I think if something is bothering me, I can deal with it without sharing it. If I owe an apology I can give one. If I need to make some other amends, I can do that. I think that is the important spiritual part - to make things right.
Some things I have as private events are things that hurt only me. Those I keep between God and myself. I have forgiven myself for these things, but occasionally I still remember them. That's okay. It's just part of me. The past is in the past, I cannot change what has already happened. I can move forward without making those same mistakes, but it's likely I'll make some new ones.
No one gets out without making a lot of mistakes. That's why we need grace. I'm at peace with that.
