I used to have such difficulty with writing theses statements. I used to freak out with them since my whole paper was supported in a single sentence. But when I realize how similar a topic sentence and thesis statement are, it takes away that freak out moment. I’ve never stopped to think about how similar the two are!
But I thought that’s what a thesis statement was for…? let the reader know what the purpose of your entire essay will be—they focus on your main idea. On the other hand, topic sentences let the reader know what will be discussed in a particular paragraph or section of your essay.

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.
