Hey Elvis, don't get discouraged. People learn at different rates and you certainly don't want to rush. Safety for you and others is the priority.
Though, I suggest you go up with a different instructor and see how things go. Not all instructors are the same and have different styles. It's not uncommon to change instructors and certainly reasonable if you are questioning him / her.
Think of it like getting a second opinion from a doc.
Another thing is if you take time off it is quite common you are going to need refreshing.
Good luck
