ترجمة - انجليزي-عبري - If I could change one thing in life.

female gender please

There is a distinction in Hebrew between saying "if only I could" (i.e. wishing you could) and "if I could" (i.e. saying what would happen if you could). I've given the translation for the second case - if you meant the first, let me know and I'll give it as well.
