cool initiative from your school to be honest, really cool
I disliked the making up stories part, everyone has family issues no matter how big or little they are. From the people who have "worse" cases in their particular life, they should be mature enough to deal with people who didn't experience as much disgraces as them, that's part of the overcoming too in my opinion. As for you, diminishing your own bad experiences will never be a good thing, I think you should always take your personal problems seriously no matter how "insignificant" they might seem next to others'.
I don't know anything about your life and might be just saying a lot of shit but at least you could take that as an advice. Just wanted to share my thoughts
