That is the problem with learning a new language when you cannot seem to find someone comfortable enough to practise and make mistakes with. When the group is too big, one becomes self-conscious. I have a small group of friends, or classmates to be exact. We chat and text one another in the language we are learning. When one person makes a mistake, someone steps in to discuss and correct it. We just keep reminding one another that making and learning through mistakes when using the new language is part and parcel of learning. It's fun, we have a good laugh together, and continue to work hard. I wish you all the best in finding some people who have the same goals as you do.
