Don't worry too much about it. As your experience grows you begin to manage the aircraft properly and get on top of it all. Some people take a long time practicing circuits but it's for the best, landing is the most important part of your flight. In your first flights you're flying the aircraft around, and in a few more lessons you'll do slow flight and stalling, where you know what kind of flying leads to the aircraft falling out of the sky. It's a great lesson.
Your instructor is there to manage your flying so it should never get to the point where you're in trouble. If it does they will take control and show you what happened and what to do/what not to do.
Remember, they will never send you on your solo if they don't feel you're ready. Just concentrate, remember BUMFRAHL on your downwind leg, and you're set. You also have the added advantage of flying in busier airspace than others, this is great experience but may take you longer to get the hang of. Keep at it this is the best flying!
Just wait till you get to navigation exercises and landaways. That's when all your local flying training amounts to an end result.
Good luck!
