Momo7, maybe you have some social anxiety. There is probably some fear that keeps you from talking to the people you admire or want to think well of you. But you can be comfortable talking to certain people, right? Like the ones that you are comfortable around, and on equal footing with? That's a good sign that you will be able to overcome this problem. You could just use some help bringing down the anxiety level when talking to teachers and people you find intimidating for whatever reason. Do you know what you are afraid might happen if you talked to them? Rejection? Disapproval? You probably have felt rejected by a teacher or a parent or some other adult that you really wanted to like you? This would be very treatable, from what it sounds like to me. Would you be able to ask your parents to let you see a counselor so that you can work on this now, before it gets more set in and starts to affect you professionally, or to limit your options in life?
