Dream

They say that if you make 1000 of these cranes your wish/dream would come true.

Dream is a wonderful thing, especially if you know what your dream is.
I had a dream too, but now I'm not sure if I have it anymore.
I'm so confused on what I want to do with my life.
I had thought that I wanted to go into medical school and become some sort of doctor, but now I'm not too sure anymore.
I guess this can be said because I screwed up my fall semester, but yeah.
I really don't know anymore and it makes me feel empty.

What is my dream? What is my purpose as a Christian? What do you want me to do in this life God?

Right now... I don't know the answers to these questions and it's bothering me a lot.
