Elisabeth, I hung out at an Enneagram forum for a while. I needed to have my husband help me with self esteem issues within the first couple weeks.
There seemed to be a lot of Enneagram 4/5/INFP/INTPs hanging out there.
I've been on other forums that allowed almost any type of trolling, and those forums both fascinated and traumatized me. I finally had to let them go because they were skewing my view of the world.
