Don't look at it as a failure. It is an opportunity to learn more and be a better skydiver because really it is. You would not want an instructor to pass you to the next level if you haven't accomplished the basic skills would you? If they did, then worse could happen down the road. It is for your best interest. In fact, I would be excited to master a skill than to be passed on when I wasn't ready. Make sense? I hope so. Hang in there. I am sure you are doing great.
