I understand your being skittish. Getting over it may take a little time but isn't that hard. First dry fire with your gun over and over with the hammer cocked and focus on the fact that you never fired till you were on target. Next for 2 minutes in the morning and 2 in the evening find a quiet place. Close your eyes and focus on your draw to target while saying. "I draw smoothly and safely with confidence". It takes 21 days to reprogram our thought process but it is well worth it. I had a horrible limited nationals years back and this was how I got over my issue.
Good luck and enjoy the process!
