Of course I'm not. You're not going to unfuck a kingdom or bring someone's mom back. I'm gonna assume that's probably not possible.
You can't force someone to forgive you. It's not possible. So you gotta apologize, and then they'll either be willing to see that you're not that person anymore and forgive you, or they'll not be willing to see that and they won't. Or they will see it and will still refuse to forgive you. There's nothing you can do about that.
And hat works both ways too. If they forgive you and you can't figure out why, you just gotta accept that that's the choice they made.
