Sure, you know how to self-flagellate, but do you know how to apologize? Saying "I'm a stupid idiot" is not the same thing as saying "I did something wrong."
People who want an apology pretty much never want to hear "I'm a stupid idiot." If someone is actually trying to get you to say you're a stupid idiot, it's not because it will make up for a mistake you made or harm you caused. It's because they want you to feel like a stupid idiot. People who care about you do not want you to feel like a stupid idiot and it hurts them when they see you putting yourself down in their name.
Plus, this can feel really manipulative. An apology is acknowledgement that a mistake was made and reassurance that it won't happen again (or at least, reassurance that the person apologizing will make an effort). Reframing the situation so that's it's all about how bad you feel or how badly you screwed up means that the person expecting an apology is getting a negative reaction to a reasonable request and is now expected to reassure whoever did harm. It's making it all about you, not about righting what you did, and it's a great way to alienate people.
I had a friend who would say, "I'm an asshole" and believed, sincerely that this constituted an apology. So I wouldn't let him off the hook; I'd say, "I'm still waiting for an apology."
At one point I said, "Dude. You were raised Catholic, for fucks sake. Do you not remember how to perform an Act of Reconciliation?"
He did not. He thought that saying he was a bad person was all that was required. So I reminded him:
Admit that you did something wrong.
Explain that you understand what you did wrong and that you are sorry you hurt someone with your choices.
Make a plan to reconcile with the person you hurt. What can you do to make it up to them? What will mend the broken trust, or restore the damage?
Sometimes step 3 becomes "leave the offended party alone." Accept that you might not be able to reconcile.
The reason why this process was codified into a religious ceremony was to teach this practice!!
It's not a "what you are" conversation, it's a "what you did" conversation.
And here's the best presentation about it:
