Well, I'm new also but I was in the same situation as you. I wasn't even sure if I liked it, but I did know I wanted more exposure to the sport. It felt like my tandem lasted like 5 seconds... I went on to AFF and I can tell you that every jump slows down more and more. I'm only on AFF 4 now but I can comprehend whats going on more and more as I gain experience. I now remember any signals I get, what altitude I was at when X happened, and things of that nature. It just takes a few jumps before you know what to expect. I say stick with it, you have a leg up on the folks who do AFF for their first time. You at least know what to expect on the plane ride and what it looks like when the door opens. Although it wasn't fear you experienced, the nervous anticipation is a really cool feeling and it a part of the reason I keep at it. Have fun!
