Physical Anxiety Box - LadyBeard Mind Launch

The LadyBeard team created a walk in box designed for people to stick up their anxieties inside. It is a very simple idea but having people inside it sparked light hearted conversations about anxiety that wouldn't be had in other contexts. 

I would like to create an anxiety box of a similar description but with two stages. Firstly the collection of anxieties in the normal manner, then a stage after that for people to attempt to imagine solutions for the anxieties or ways for people to feel better. Fantasy ideas anything goes!

I would need to make a movable box to put in a good location. library foyer probably.
