Anxiety pills?

Hi, is there any anxiety pill that I can take to overcome my anxiety to skydiving? I already did the tandem (jump with instructor), and I already took the skydiving course, but the first time that I was supposed to jump alone I frozed at the door, and could not jump. I am preparing now to try doing it again, but I get really anxious since the night before, and anxiety increases a lot when I get to the plane. Is there any pill that could help me overcome anxiety at least for my first jump?
