The mind control that they use is irreversible.
Not so. When you realize it's mind control it is completely reversible.
However I also realize that some people need their cult - they cannot survive without it. As you mentioned earlier, suicides are way to common among both active JWs and ex-JWs. I suppose it's better to be in a cult and be alive than to be away from the cult and not be alive.
All the best to you, whatever you choose.
