Stuck on my Narrative

For my English class, I need to start writing a personal or fictional narrative. I want to start out with the personal narrative, but I have no idea what to write about. Sure, there have been plenty of things, even crazy things that have happened to me, but what can I really write an interesting paper on? I don't want to go too sad but I don't want to go too happy either. I need to figure it out soon though, because the first draft is due this Friday! Calling on the writing gods to help me with this one! (I'll probably actually just talk to my mom for ideas...)
