Of course! First of all, you shouldn't be afraid of making mistakes while talking to people in a foreign language. Why? Well, because mistakes are what makes you learn the language. You must not be ashamed of your mistakes when talking to someone who knows how to speak the language you're learning. If the person you're talking to is kind and nice (which is very common) they will try to correct your mistakes in order to make you improve your learning skills. The thing is that, don't be afraid of making mistakes, because if you didn't, you wouldn't learn anything at all. So, don't worry too much about grammar for now and just focus on speaking and on gaining new vocabulary, so then you can take advantage of those and improve your grammar. I hope this can help you, and remember, don't be afraid of making mistakes! :)
