My ex-wife is a chronic OCD sufferer. Im talking plastic on her couch, eating food over the sink, disposable cutlery etc. I dont think Watchtower caused her OCD but it definitely magnified it.
She and her mother both have red scabby skin around the eyes, elbows, scalp and behind the ears. My ex-wife's condition vanished when she stopped going out on the ministry and reduced her meeting attendance. She also doesn't study anymore.
In my case i was having anxiety attacks in the final two years of my JW life. At the time i didn't know what was causing it. I would feel like i was about to throw up so would have to walk around, pacing up and down corridors or outside singing or talking to myself to distract my mind until it passed. Sometimes i'd have to leave the KH and walk round the block for an hour. One thing i found that 100% worked was watching porn for 2 mins. BAM! distracted and anxiety gone.
When i finally left woke up to Watchtower indoctrination the anxiety disappeared. I was still going along with the facade trying to fade but i was a lot happier.
Funny thing is. My girlfriend has lately been having anxiety attacks due to being a fulltime teacher and studying for her Ph.D. I told her the porn distraction thing i did and she tried it and it worked for her too.
So, in my case, Porn was actually helpful to my mental health and not toxic like Watchtower claimed so many times in their rags. The Watchtower however, was toxic to my mental health.
(P.S. In no way am i advocating porn for everyone. I know it can be an addiction for some people)
