I am afraid of my PSAT scores...?

I been studying for my PSAT for a long time. I am a sopre and this PSAT should not really count but I am afraid of my score, mainly because it shows my potential and where I am. Also I really don't want to get a bad score to make my dad depressed with me and me feel stupid. I'm so afraid!! Help. I don't want all my work to go to waste
