If you see, I was broken makes sense to me. It means you're having a very difficult time due to say some tragedy.
But I want to say it like Once you are broken, it will always xyz. But to me, it seems tragedy happened recently and you're still affected a lot. But what if I want to say the same for a tragedy that happened long ago? Does the following sentence makes sense?
Once you have been broken, it will always xyz. My specific doubt about this is: Does have been here mean that somebody else deliberately and specifically caused trouble to you? Is the sentence hinting to some other person?
