Fool, in fact, I care about you, but you don't understand. I really have to do this. How to say it in English?

Fool, in fact, I care about you, but you don't understand. I really have to do this.

You idiot, I really care about you, but you don't understand. I really have no other choice.

The translation of Fool into dork is an intimate and lovely expression in English, which means the same thing.

I think this translation is more authentic. I translated it carefully. I hope it helps you:)
