Hmm I definitely do need to relax, but it's a bit difficult. When I'm on stage I automatically go tense, and then I think "oh no, I should be relaxed or I'll look stupid" and then I tense up even more, and so on, and so on. So that is kind of just the whole problem with my performance issues.
I always find it weird staring fixedly at the same point for a whole song... That's what my teacher always used to tell me to do (find a point in the middle distance to look at), but I just always feel really strange doing it.

Halka, if your daughter finds any solutions to performance anxiety, let me know please.

lucky, maybe it would actually help if you got away from the "standing still, try to find a point to look at"-idea and started to move and let your eyes wander.
Move, move, move and let it out! 
It is not appropriate for every song to run about like a loonpot of course, but this very common classical ideal of "come una statua" does not really help with performance anxiety.
We all know that we get rid of excess adrenaline if we move. If you try to keep still, you'll only make it worse. Allow yourself to move, wander around on stage etc. (you will find strategies to incorporate it in your performance without it looking stupid). Communicate with whatever audience is there, it doesn't matter. Just do what feels natural.
I was exactly the same as a young performer and crippled by performance anxiety (so bad that my knees were shaking and my voice started getting unstable), but it can be overcome. If I can do it, everyone can, because I was quite a nervous wreck
I am still nervous when I perform today,
and it is good that way, because it shows you care and gives you that extra-boost you need to emote. You just cannot allow it to wreck your performance. It is no weakness to be nervous however - accepting this fact is the first step towards getting to grips with it ...
