At this age?...It's too early for a feeling like that to come into mind. Just go with the flow and make some efforts but don't get into too much pressure of doing something that it'd affect you negatively.

hi Saccharine
That is what is termed an existential crisis. You can now reinvent yourself. Perhaps adopt an archetype: Witness, seeker, creator even. Whatever enjoy your new life. You are free.
Best wishes

Think what happens when you throw a stone into a calm pond. It ripples ! Everything you do is like rippling, it affects others in a good way.

We just can't always see the point of it, but its there and what you do will affect you. So be a good person. That's the best you can do.

Very soon you will realise that everything you do is important to a lot of people.

Welcome to being an adult
