I can't seem to make up my mind!!

Now is the time to make up my mind about my future, but i can't seem to do it!! I'm so scared of making the wrong choices and adding up hating what i am doing!! I really dont know what my interest are, i mean, i really dont know where to start and everything...is this because I'm in a identity crisis??I'm feeling so messed UP!! COnfused!!!i Need help desperately......i have a deadline to meet....can I make up my mind by then????
