CatsPHiddle,

You just need to learn a new skill. You've been playing from dots so long that that is all you know. But you know the saying "practice makes perfect." So start practicing playing by ear. And memorizing? Start with a couple of bars, then move on to one eight bar part. Once you've got that down the next eight bars are a repeat of the last eight, most likely. If you're looking for a magic fix from somebody you are wasting your time.
