Find a purpose. Without purpose, life is pointless, other than to subsist and indulge our senses; which do not bring meaning.
Many do, it's not a fault. Read about the state of your community, your state, the nation, the world. All of these have needs, not all of them met. Get to know yourself and what makes you tick. Then reflect on how you might apply yourself to any of these. Not to condescend, but you are still young, so be patient. An answer will come to you when you are ready. Self doubt and fear will challenge you, but do not allow either to conquer your will to live a meaningful like. One by one, the world is changed.
