Your parents are entirely two different individual, though they have something in common....and that is YOU. You have mentioned that you have grown older, it means you are now more mature, that is great news. You are what you are now because of how you were brought up by your parents, even though they are apart. Use your maturity to see things in a positive way.
Surround yourself with nice friends, make your time productive, you could join community activities, be active in school organizations, and even join
teen boot camps . Making yourself productive is a way of showing your parents you love them both.
