Learn Sentences Not Only Words
In a way, this will take the pressure off too. When you learn a new word, try to memorize a couple of sentences that contain it.
There might come a time when you can use one particular sentence with little, or no alteration at all. Unfortunately, many people learn words by heart, but have no idea how to use them in a sentence.
It will be such a relief not having to worry about whether the sentence is correct grammatically or not.
