Am I wrong? <parent problem>?

Its true that everything you have now is because of them and that you should obey your parents and strive to make them proud. Its also a good thing that your parents expect nothing but the best from you in life. It breeds good virtues that will stick with you through to adulthood. You will thank them for it later. If it stresses you out you should talk to them about how you feel. Im sure that they aren't heartless. They'll listen to you. But be respectful and remember that everything they do is what they believe is best for you in the long run.
