The others have given some good suggestions, such as finding someone with similar interests, and being aware that most language learners are nervous and unconfident, or perhaps talking in Chinese first. If you are particularly nervous, I would first suggest that you tell any potential language partner that, so that they don't mistake your nerves for dislike, or disinterest. Secondly, I think that it helps a lot to start to communicate by written conversation first. I find that that is a good way to start to get to know a new person, and get over those nerves, and once you have done that, it's a little easier to voice chat. Another thing that might help is to think of a range of questions to ask, or things to talk about before your talk. That way you won't get even more nervous if you can't think of something to say.

Or you can speak Chinese to your partner at the beginning and make him or her nervous first.

Do you feel nervous when you have conversations in Mandarin or Cantonese? If not, then you just need to have more conversations with native speakers. Most of the people on this site are working hard to learn a new language, just like you. So remember that we feel nervous too when we try to communicate with you. Try to find someone here to chat with that has similar hobbies as you and then talk about those things together.

(continued) I have noticed that many students fear that their English speaking partner will demand that they engage in all manner of spontaneous dialogue, which places much stress upon the student. I know for myself, this is never the case. In my first lessons with a student, I do most of the talking. I ask the student to repeat what I read a phrase at a time. So, the idea that the student must "think fast" and form complicated sentences, is just something that does not happen in my lessons. .

Hello Alina: I do not think that it is helpful to think of the issue as something that one can "overcome". That suggests some sort of personal "power" over the feelings. It is much more productive I think, to work Within the feelings of powerlessness and use the power that has been invested in those feelings. That energy can be turned to your advantage. For example, you have now informed others that you have anxiety about the issue. Your solution is to carefully look through the tutors, language partners, and teachers, and find the one or more that seem trustworthy for you. Those of us who tutor are, after all, familiar with the difficulties that foreign students have. Therefore, when we practice English with you, we have devised special methods which guide you and put you at ease. Once you discover just how gently and tenderly your feelings will be regarded, your difficulty will pass away.
