I remember my own great purge and how empty and sad I felt inside while throwing it all out. I knew TTATT and I had no regrets for leaving, but somehow I was sad. That literature represented a feeling of security, albeit false.
Discussing the experience with another former JW, I was counseled to view it as leaving a once cherished but now toxic relationship. You know you're doing the right thing but the human in you still hurts.
It gets easier.
