Looking for "brick in the wall" youth group activity about conquering difficult emotions

I saw a beautiful article from a youth group leader (I think this was a church ministry group)  who used the large corrugated paper blocks.  He had the teens think about a feeling that feels like an obstacle that interferes with their life.  They all write a word that represents the problem like "fear", "anxiety", "loneliness".  The students start placing their bricks on the wall.  They keep adding to the wall.  (Part of the healing is naming what is bothering you.)  I thought the author had a great way to help teens think and safely share how they feel.  He had a great narrative about the conversations and questions he asked.  I thought I saved this article, but cannot find it.  Anyone ever hear of this?  If so could you share what you know about this activity?  Thanks
