Hey Olivia,
I second the advice to consider doing this in a group setting. Based on the conversations I’ve had, everyone seems to value a stronger social connection with like-minded people and/or others feeling the same problem. My solution was always based around a group discussion, but its evolved to put more emphasis on connecting with others in the group, strengthening social bonds, and providing support to one another. The group setting will also take pressure off of you to be ‘all-knowing’ and instead allow for many different perspectives which is always valuable.
Your discovery about the root cause of accumulation is very interesting and I think makes sense. I look forward to seeing how you work with that knowledge!
