Are you learning English grammar but do not understand native speakers and can not say anything?
You need to listen more and more every day to understand and speak English fluently. Grammar is useful but not so important. Children do not know grammar but understand and speak very well. So the main idea is to listen and listen to the same English stories or dialogs 50-100 times for several days. At the beginning you can only listen, then listen and follow the text by eyes.
