How can i write about this?

for english class, we have an asignment to write about a ight that really affected us, and how we fight. i really want to write about my fight that i had with a friend, over something really dumb, that turned into something really serious (her telling me that she used to be suicidal). except there is going to be peer editing and this is really personal,so how can i modify it to make it a little less detailed
