I am really really confused with my essay :( can someone PLEASE help me?

If your professor has seen this paragraph, then I understand your frustration. The last sentence of your paragraph does give an indication of what you want to argue: 1) that Disney's portrayal of women is divorced from reality; 2) the portrayal affects how girls perceive their own appearance; 3) and this results in many girls having psychological problems. If I'm right about then, then I'd suggest that you stop revising the first paragraph and write the rest of your essay, if you haven't already done so. When you've finished writing your essay, your argument may have developed, in which case you will need to revise your thesis. When you do get back to revising your opening paragraph, perhaps you could drop the references to secondary sources (since they distract your reader a little from focusing on what you yourself will argue. And when you get back to revising your thesis, taking into account that your professor may want a very clearly stated thesis, then perhaps it would help (and surely it wouldn't hurt) to begin your thesis statement with the words "In this essay, I will argue that, X, Y, Z." It may seem clunky, but that kind of sentence appears in articles written by professors all the time. If you want any more help, I would suggest visiting a free essay review site like Essayjudge.com (which I know about because my friend is writing great reviews there; and, yes, I'm writing this because he asked me to help him spread the word.)
