''how my perspective of the world has changed as a teenager'' pls someone help

When your a teenager your life becomes more difficult as your slowly growing into adult hood. You start to leave your pre-teen days behind. And you now realize that you must start thinking for yourself in almost ever situation. Paying bills,driving a car,etc…you realize the world can be a horrible place and that your simply a grain of rice in a huge bowl. Your parents won’t always be there and you now think to yourself who can I truly rely on? Will there ver be someone who will take care of me like they did? Or will I simply take care of myself for the rest of my life with no reassurance or comfort from a trusted outside source. So in conclusion your life makes a 360 turn and you now basically step in the exact direction as your parents and carve your own way in life.
