Hmph. I think you're not giving yourself any credit. Forgiveness and forgetfulness are only the same thing in trite sayings.

I believe you're more than capable of showing kindness to yourself without forgetting the things you regret, that drive you to be better. In fact, I think it's likely that, whether or not you realize it, you're only holding yourself back from growing by clinging to such self-loathing.

But I've lectured you enough, if at the very least we can agree none of this was your fault.
