I knew of many people who suffered from depression in the org, although I don't know if I would go so far as to say they suffered from this BECAUSE of the org.
I can only relate my own personal experiences -
I suffered from depression in the org.
I suffered from anxiety in the org.
I now have quite bad paranoia and anxiety, from what I KNOW was because of my experiences in the org.
But, I am working through it and getting alot of help, and as a result, I am much happier now.
I do not beleive that this organisation was one of "happy people" that's for sure.
