Welcome to the board. It's not easy at first especially if your raised in the JW (like me) it takes some time to heal. I am so much better now that I am free and there is no way in hell that I am going back. I like to compare the feeling to a animal who spent most of his life in captivity, you send it out in it's natural environment and it becomes scared and it must learn how to survive. For us it is similar but once we have tasted what it really means to be free and depend on our self you can never go back.
When it comes to the future of the world try to accept the things you have no a control over, the earth and life on it has changed many times for over 4 billion years so I think it is a bit arrogant to think we little humans are going to do much damage. I find also that this world today is not as bad as the JW would make it out to be, try and inform yourself on the good tings we humans have accomplish compared to what our world looked like before. Take back the control of your life don't let fear and a publishing company convince you that you need an org. to make you happy.
