I'm on jump 27 and I was feeling exactly the same up until very recently. I was absolutely fine until the door opened and I was getting in the door. Some jumps I almost thought I wasn't going to be able to get out. Every jump I'd done was a 'normal' fwd exit as AFF and I hated it. The second I was out, I was absolutely fine, even when completely unstable. It was just the exit that put the fear of God in me. Anyway, at the weekend I started FS1 training and my coach asked me to exit from outside the plane, jumping off backwards. For some reason, all fear of exiting completely disappeared. Holding onto the bar above the door made me made me feel more secure getting into position, not looking at the ground helped massively and the exit was so much more refined, stable and controlled. Have you tried different types of exit? It's certainly helped me out hugely.
