You have to learn how to protect your feelings.
You know it's wrong - don't look to the elders for help and don't recognise their authority. The only authority they have over you is what YOU give them.
You have not wasted your life, you have learnt a lesson and its good to understand how con tricks are played so you can avoid them happening again. Watchtower is not the only media organisation that plays games with spin and peer pressure.
Take one day at a time. Respond to the moment rather than trying to think too far ahead. You might forsee things that never happen which make you panic. Treat everyone as you would like to be treated yourself but be cautious.
I know someone who has just got their ENTIRE family out (multiple generations plus some others and maybe even more to come). The key to getting them out was BE KIND, BE A PERSON OF INTEGRITY and BE PATIENT. Just as you want freedom to think for yourself so does that other person. So don't assume you will lose your family but if the worst should happen:-
Mark 10:29,30
Jesus said, Truly I say to you, There is no man who has given up house, or brothers, or sisters, or mother, or father, or children, or land, because of me and the good news, Who will not get a hundred times as much now in this time, houses, and brothers, and sisters, and mothers, and children, and land--though with great troubles; and, in the world to come, eternal life.
