Interesting question. I think in some ways being raised a JW helped me with certain aspects of self-esteem. I read well, speak in public well, and as I was giving #4 talks at a very early age, received much positive reinforcement from those in the cong.
However, overall being raised a JW really takes it's toll on you. You are absolutely destroyed in school for being different. And in the congregation, your supposed "haven" from the pressure of the world, you're constantly being told that you're not doing enough - can't you pioneer, can't you give more $$, or more time, or whatever. You never feel that you're good enough. You feel bad for every 'sinful' impulse you have, like no one else in the cong has them. If you're not given privileges, then you are obviously doing something wrong, or just plain not good enough.
Jesus said that his 'yoke was light' - obviously he was NOT raised as a JW........
