Guilt feelings at never having done enough are common among JWs.
That's because the whole legalistic WT system operates by fear and guilt.
Having a constantly dissatisfied authority figure like the GB/CO/elders driving you is hard enough.
But when you realize that you are feeling guilty even though no one has said a word to you, you realize how powerful the mind control is.
The magazines' portrayal of the WTS as Jehovah's happy organization adds to this.
First, they make you feel like a constant, personal disappointment to Jehovah, a sorry excuse for one of his witnesses.
Then you feel completely alone beause you aren't experiencing the happiness and joy of the spiritual paradise the magazines portray the organization to be.
Since you can't talk about it for fear of looking weak or even apostate, you don't realize that virtually everyone else at the hall feels the same way.
