You describe my Cog. Diss.to a tee when I was in Mr Punk Sir !
I think that struggle gradually tears you apart, the real you is constantly fighting the "you" that we imagine we should be because of the ideal Mr or Ms Jehovah's Witness that is portrayed by the W.T.
In my adult life I used to tell myself that jehovah was a god of love and would understand my limitations, which amounted to not being able to be the good little sheepie dubbie,and that even the WT didn't really expect us to attain those unreachably high, totally unrealistic targets that they set.
I beleived they wanted us to aim high, and then perhaps achieve a level that made us acceptable, simply by aiming higher than we could really achieve.
It is only after I left, but amazingly so quickly after I left, that I realised the "cult persona" was totally false, totally not me, and that it was not even a good thing if I had achieved the total subjugation of the real me.
It was such a relief,and feeling of sublime peace, to realise I could be completely the real me, and still be a good person in all things that in truth matter.
