I'm guessing you're a new pianist - hope that's right...
This is natural for everyone.What helps me is finding times to practice around people, but without having them pay strict attention to me. Like if my friends and I are just hanging out and talking to each other, I know I can play without drawing much or any real attention, and that makes it so much easier.
It doesn't go away with time... it's all in the confidence. For others, I get the nerves as if it were my first time. I still feel light-headed and heavy-finger in front of of piano teacher but I'm fine with my family (my siblings are all piano-washouts so I feel confident) or anyone whom I know won't be able to tell how well (or badly) I'm playing.
