The International Cultic Studies Association, along with some of the mental health professionals affiliated with them have support groups for people who are recovering from high-demand, controlling groups, and those who have lost loved ones to such groups. They have retreats, conferences, support groups, a magazine, a library of resources, quite a lot of information. I know two psychologists, a married couple who have a private support group, and also provide individual counseling around the cult experience.
I ran a workshop for them once, a workshop specifically for current and former JWs.
Please check them out. I don't necessarily endorse them, nor do I provide any review of them. Every person's experience is different, so I encourage you to check them out and judge for yourself.
I am going to check FOOTSTEPS myself and see what they are all about.
