I want to translate a sentence from Spanish to English.
Me haces tanta tanta falta
I just ran this through the machine translator. It didn't come out very well. Nevertheless, I often use the machine translator to either get me started on a translation or, more often, to verify that my Spanish was written correctly. The machine translation may give you some clues. After you've tried that, as Fred suggested, come back and tell us what you've got. We can either confirm or point you in a different direction.
You have to try to translate it yourself before the rules allow anyone to help you. If you want help with that go to the dictionary and look at the individual words. Come back after you've given it a first shot.
hacer falta -> to be necessary
me hace falta suerte -> I need some luck
me haces mucha falta -> I really need you
