Essays / Need some input on what to write about for personal experience essay. [5]

I've been asked to write an essay with this prompt " Describe a personal experience that has profoundly changed your perspective on an issue of regional, national, or international significance.

My problem with pinning down an exact experience to write about is that I'm not sure what would be considered a national/international issue. My immediate idea was to write about my experience of domestic abuse as it changed the person that I am today in a significant way. Would you consider domestic abuse/violence a national issue? If not, then I need to keep searching for my topic.

Thanks in advance for any input.
