Anybody good with essay structuring? ?

hello! i am trying to figure out how i am going to organize my paper, and i have so much information and cant figure out how to do so!! My thesis is about how media representations( like photography and video) affect war. It has to be eight pages in length, so i want to try to break it down into small paragraphs. Okay, so i was going to write about how different wars in the US, starting from Civil War, then WWI, WWII, the cold war( Vietnam, Korean War) to the current Iraq war have all been affected by the media. I think i will focus on photography, video and newspaper... I was planning on going through each war and saying how these medias affected them, but i fear that will sound to repetitive and nonacademic. Also, i am going to argue( my thesis) that these media representations have caused Americans to form negative views on war and how they bring about the realities of war. With this said, should I also dedicate a paragraph to contradict my thesis to show a different side to it? Or incorporate the contradictions? Can you please ist me in how to organize this essay? PLEASE!! i have been stressing over this for weeks, and i feel that i have a good idea about WHAT to write, i just don't know how to format it! thank you so much! i appreciate it sooo mucch!
