How to say "Knowing that I hurt you is breaking my heart"


How does one say:

> Knowing that I hurt you (your feelings) is breaking my heart.

"Breaking my heart" I think I know:

> 胸が張り裂けています。

but the first part and how to connect the two I'm clueless about.




I think the sentence "Knowing that I hurt you " can be translated as
あなたを傷つけたと知る.

I translate your sentence as あなたを傷つけたと知り、私の胸は張り裂けそうだ.
