Love the idea for its simplicity. It is easy to implement and has potential to impact the overall psyche of the patient. The tools can be customized according to the symptoms and support groups can be formed online to further scale acceptance of the idea.

Compassion box is a holistic solution as it impacts the daily interactions of the patient and it is multi-faceted as it can impact different kinds of interactions.
