How do I feel after writing my essay

I am exhausted and my brain hurts. I feel like I can even think clearly anymore. I am also anxious about my paper, thinking that maybe I didn't do enough or that I did it wrong. I am not a very good communicator as far as writing goes I can talk and explain what I am trying to say it is just very hard for me to put pen to paper. I also have another problem and that is trying to comprehend what I have read , and transform it into my own train of thoughts. This has been a very difficult class for me but I only feel that it has enhanced my skills in writing. I will take with me the thing that I have learned in this class and put them to further use in my next courses. Thank you for your support and feedback.
