You really need to share you experiences and observations. Did you discuss your feelings about you comfort level, and preparedness to dive with the instructor?
Are there alternative instructors anywhere near you that you can also speak with? Interviewing, to find the instructor who will spend the time and effort with you, both prior to your class, and as long as it takes during class, to make you feel secure and prepared,is more than 1/2 the battle. Not all instructors are the same. Some will rush, to get you through their class, and out the door, while others really care, and lean over backward to make sure they produce safe comfortable, and skilled divers.
Possibly you are better prepared than you think, and a few lessons with a new instructor would be all you need to become more comfortable with those skills you do have, but are yet unsure of.
