well is it talking to a boy or a girl....because "you" can be boy or girl...so maybe you would want to say exactly. it would be
"Ani tamid eshmor alaych-girl, alecha-Boy..."
that would be the exact translation, but it would be prettier just as
"Tamid eshmor alaych/alecha"
without the Ani, but thats just my personal thought.
i dont have hebrew on my computer so i cant write it in hebrew but someone will just say if you want it said to a boy or girl.
i hope that helps a little bit, sorry i dont have hebrew letters on my computer but at least you will know how it sounds
