I also had to cut away on jump #18 during training due to tension knots that caused me to dive to the left and spin rapidly. I knew that I had to jump again or the fear may grow more intense, so the first thing I did was manifest myself for the next load, which was my first jump without a coach. I was definitely very nervous because of the cutaway but it was such a great feeling when I was under a working canopy.
I've jumped 4 times since the cutaway and it has gotten better. I find peace of mind in the following:
-I performed proper emergency procedures as I was trained to do
-My gear didn't let me down. It did what it was supposed to do. The reserve kept me alive. I'm still here!
-Understanding that cutaways are inevitable, that's why we have reserves
-I got my first cutaway over with early in my skydiving career. I'm more confident that I'll be able to react properly during the next one.
-Sure it was scary, but it helps me to not become complacent and disregard safety concern
-Research on why my particular malfunction happened, what I can do to prevent it in the future, and how to best react if it happens again. As well as thoroughly researching and practicing all malfunctions so that the response is second nature
-I have a great story to tell
With that said, I still have jitters every single jump, even before the cutaway. Overcoming that fear is part of the fun for me. Once I jump out that door it all melts away. I love it! It does get easier though. My last jump I was even thinking how much less nervous I was and more so looking forward to doing front flips on the exit. Hope this helps!
