Obviously native speakers can speak their language well - but you should not compare yourself to them!! If they were learning your language, they would have difficulties and a strange accent too. Don't be shy to use the language that you have at this time, and as you learn more (and always read as much as you can in English) you will feel more comfortable. It is a good idea to think simplistically - Subject, verb, object, so that you don't get caught in complex structures, but as time goes on, trying new structures is what will help you improve. Keep asking questions, talking, writing, and reading.
