Why do i suck so much?

So today was my first dat skiing this season. I had fun but i realized how much i really suck. I am good with carving and the general skiing techniques but i can never seem to progress in the park. I have a problem with just being too scared. Call me a pussy if u want, but i know u guys were all in this same situation at one point and i just want your tips and how u guys get the balls to try stuff.
