I can sympathize with you, as I shared the same woes. Don't torture yourself though. Quite often the ornamental form simply hides the lack of intellectual depth in the content. Free yourself from such thoughts and the rest will follow.

I really recommend "The Economist Style Guide". Please read through it, then read again to see how it was applied to itself (!). Then write a short passage, and revise it to adhere to the recommendations -- don't be surprised if this will need several passes though!

You will be surprised how much this can improve your writing, but also structure your own thoughts.
