Learning a language can be a tricky process, but it’s important to remember that it is a process.
Having learned 20 languages so far, Canadian polyglot and LingQ founder Steve Kaufmann’s advice is to not focus on the grammar. Constantly thinking about the rules while attempting to speak only makes it harder.
Investing time (often several months) into listening, reading, and practicing words before trying to speak a language will help you feel more comfortable with it. You will make mistakes, but you will learn from them and people will be patient with you.
