Don’t be afraid to make mistakes!
You are learning a second (or maybe third!) language, and that is really, really awesome. Many Americans never learn another language. Don’t be embarrassed that you don’t speak English well, be proud that you are learning a new skill.
Don’t let your fear of making a mistake stop you from speaking to people in the community. Remember, you will make mistakes, and that is okay. Mistakes are how we learn and get better!
