my topic is depression and then write a essay, and include those question.

First, what is your topic? Why are you personally interested in the topic? What do you hope to learn through the process of researching and writing this paper? What is the lens through which you will view development across the lifespan?  For this example a student has chosen to write about the impact of having dyslexia.  An introduction is needed that acquaints the reader with what dyslexia is, how and why it develops.  Thinking developmentally – at what age is dyslexia usually identified?  Is there a benefit to earlier diagnosis? What is the lifetime progression of dyslexia?  Does it get better? Worse?  What kind of intervention is helpful, and at what life stage?
