How I feel about my essay?

I feel good about, I had to extended the length of the essay so another 3 pages to meet the requirement. but I feel pretty confident that I did good work. I know there is always room for improvement though, the more I write the better I will become. I think I just feel tired  from writing the paper and being overwhelmed worrying about if everything is as it should be. In the future I would like to write about other health topics such asthma, addictions to prescription drugs.
