- Discovering Your Authentic Self - (personal identity)
- Dealing With Isolation and Loneliness (shunning)
- The Five Stages of Grief/loss (Kübler-Ross model)
- Examining Our Beliefs: Identifying the false and harmful (dysfunctional) core beliefs which are the root cause of our on-going difficulties after leaving
- Treatments & Interventions - seeking treatments from working with mental health professionals to self-help
- Psychoeducation - this is closely related to #4 above, but is frankly more technical
I'm with @Flipper and @Reopened Mind with what I'd rank as number one. There is just something so crucial about uncovering the authentic self in order for the rest of the recovery to fall into place.
In my opinion, your recovery is futile if you've only worked hard on healing the cult persona. It's quite tragic when you have ex-Witnesses who carry their WT narrow-mindedness, prejudices and paranoias with them in all the other areas of their lives. Relationships suffer, friendships are slippery and escapism is a more viable solution than rationally going head-to-head with the issues at hand (how simple it is to substitute a Watchtower with a drink, or a three day convention with a bender). Self-loathing is a key ingredient in WT's toxic cocktail, and it can remain in one's system for life if unaddressed.
Providing people with the right tools (or even questions they need to ask themselves) for uncovering their authentic selves can empower them to deal with the knock-on effects of leaving a cult, such as the strength to deal with the loneliness. One is never truly lonely if they've discovered and befriended the stranger that's been inside them their whole life.
