Last year I attended an XJW workshop, I wrote here about my experiences. The workshop was conducted by Dieter Rohmann (http://www.kulte.de), a psychologist and a collegue of Steven Hassen. The idea came from a support group in the South of Germany.
A woman and me were the only participant from the north of Germany. We noticed that there was nothing similar in Northern Germany (except two very religious movement).
It took almost a year but now we decided to start our own support group in Hamburg. In Hamburg there is an organization called KISS (German acronym for Contact and Information Point for Support Groups). They help support groups of any kind, mostly from a health background but there is i.e. also a group of former members of the Newapostolic Church (which is the biggest Christian cult in Germany).
KISS provide a room and even distribute the groups' press releases. I am very happy that by means of that we are independant from ressources of any church.
The first of our monthly meetings will be in the beginning of October.
So far I have advertized on the Internet but I am excited how many will react to the press releases.
