Get it out of your system and just allow yourself to keep writing in that style until you exhaust it. Normally, one of three things will occur.
1) You get cleansed.
2) After awhile you look back on what you've wrote and feel disgusted, erase it and then actively try for your creativity
3) After writing for a while in someone else's style you begin to develop you own
Either way, it's a win/win situation. Anyways, don't be ashamed, there's plenty of proclaimed authors who were heavily influenced by their contemporaries or authors that expired them in the first place. You know those discreet little references to Shakespeare, the Bible, Thoreau, Poe, Plato, ect? They're like an author's way to tip their hats to those who've inspired them or even their text.
