No one is keeping you from your faith or the exercise of that religion, so be respectful of other's beliefs so that they too will never force their beliefs on you. Again if you want to pray at school, find a place to do so. If you want to pray before you eat do so. But don't make a spectacle of it. Christ himself advised us to pray in private that we are not hypocrites.
