I would add the loss of self.
In the organisation you are taught never to think too much of yourself, not to celebrate your achievements or develop skills outside the watchtower's activities. From children you are taught to have no self esteem and to trust elders and appointed men completely. You are not encouraged to think for yourself, make your own judgments or pursue knowledge. You live a half life throwing away your potential to slave for an organisation that does not care for you or your well being. They squander the lives of their followers simply because of greed with no thought of the misery that this inflicts nothing could be more selfish or self serving.
