I'm so sorry! Congratulations on having lived through all this pain and rejection. Do you know of others in your area who have chosen the "apostate path" so you might have someone who understands because they've been through it, too? Do you have a job that pays enough for you to live on? Did you graduate from high school?
I'm sorry about all the questions, but I am trying to assure myself that you will be able to get out of your situation and start a real life. I am lucky that I had a pre-JW life, so it was not as hard for me to function in the real world.
At your age, all I knew how to do was obey. I recommend that you read Dr. Wayne Dyer's book "Your Erroneous Zones." I read it just before I exited the org, and it helped me to let go of guilt and fear and begin to think for myself without having to ask someone else what I should do every time I had to make a decision.
It sounds like you have learned enough to get started. I hope you will take one day at a time and be patient with yourself and kind to yourself (hard to do when you've rarely heard anything good about yourself).
Best wishes for a happy future. Keep us posted on your progress.
