How do you get an old yahoo account back?

i deleted it two years ago, but my Y!A still comes up on google with embarrassing stuff, so i want to put the stuff to private, so people dont see the questions when they google my name. i feel sick about this and i've tried to get yahoo to delete the question, but i've sent something over 10 times and they won't, so i guess i need to go on that acc. please help!!
