The real question you need to ask yourself is this: What does God want me to do with my life? God made you and knows all about you -- and He also knows what's best for you. The most important thing you can do is turn to Him and ask Him to show you His will.
What is His will for you? I don't know the full answer -- but I do know part of it, for God's will for you is the same as it is for everyone: That you would come to know Him by giving your life to Jesus Christ. We are separated from God because of our sins -- but by His death on the cross Jesus Christ made it possible for all our sins to be forgiven and cleansed. Don't try to live without Him any longer, but by faith turn to Jesus and commit your life to Him.
Then seek His will for your life. He may not reveal the whole road to you right now -- but all you really need to know is the next step. Make His will a matter of prayer... assess your abilities and interests... and then trust Him to open the right door and lead you. The Bible says, "Whether you turn to the right or to the left, your ears will hear a voice behind you, saying, 'This is the way; walk in it'" (Isaiah 30:21).
