There are too many, all equally as bad as each other depending on the time period that I lived through, but here are the ones that are at the forefront of my mind at this moment:
1. Upon joining at the age of 14, having my lovely, close, non JW relatives and friends replaced with a new 'family', and from then on having my friends chosen for me among the most 'spiritual' members of the congregation, most of whom I had nothing in common with.
2. Being deprived of a career.
3. The shock of becoming concious after reading a collection of Russell and Rutherford's books full of 'old light' and having to keep quiet for fear of being disfellowshipped.
4. Depriving our children of a normal early childhood. Thank goodness we left while there was still time for them to enjoy a few childhood years away from the influence of the WTS.
5. The frustration of not being able to talk openly to my JW relatives about the truth about the 'Truth'. Whenever I attempt to do so, their eyes usually glaze over and I know it is not worth the risk of being shunned by them.
