I'm not changing as much as I'd like to
What is it that you would like to change about yourself?
My rebellious nature.  I don't want to be a stupid rebellious teen anymore.
It's good that you are trying hard to improve yourself and are willing to admit your faults.  I can already tell that you have made a lot of progress, but if you need help, there are others who can provide assistance.
Maybe that's true.
It is certainly true. You will mature as time goes on, but maybe putting yourself in more uncomfortable situations will allow you to loose your rebellious nature. These situations will allow you to grow as a person which will change your perspective on life.
