Your thesis statement should be an important idea, the main reason for writing the essay.
When students write essays, it is to get a grade, but when adults write essays it is because they want to make a special point. Imagine no teacher is telling you to do anything, and you just want to write an essay to explain this important idea.
So, what is your idea? Do you want to tell people a list of strategies for dealing with culture shock? If so, your thesis statement should tell about the list. Put the thesis statement in the 1st paragraph.
