not a song - translate into Hebrew

Hello.
I'm not sure if this is the right place to post it, but I need a phrase translated into Hebrew.

"my strength cannot be broken"

I can't trust the online translators, so if somebody can translate it for me and write out in Hebrew letter, I would be very grateful.

thank you & toda raba

"my strength cannot be broken"

כוחי [הכוח שלי] לא יכול להישבר

kochi [ha'ko-'ach shely] lo ya'chol la'hi -sahber

thank you so much!!!

You are welcome, Nikilas
