I can't write, I swear..

I'm having a big problem when it comes to academic writing. It was horrible for me. For position paper and research paper, I have to write thousands of words to finish both task. I can't write something that I am not interested in, such as literature. It takes a long time for me only to think about the topic. Seriously i need help. i don't have much time left. It is crazy when I think about it. Plus I'm not interested to do so. i feel discourage, hopeless, tired and so..
