Surfacing,
Great to see you come to the realization that the JW ?truth? is not the truth. I have had a very similar experience, as have many others here.
Does it get easier?
Absolutely. Following a period of grief and confusion, you?ll eventually get back to yourselves.
I'm getting better with the panic attacks (doing my own research and realising that it is because I have a lot of unresolved issues, not necessarily because the demons are attacking me), but I still have this terrible, impending sense of doom. Am I on the dark side?
Nope. Just guilt from indoctrination. You?ll get over the guilt as you prove your suspicions were true, and become more confident that you?ve made the right decision.
Have I really lost all hope of seeing my father because of the way I'm thinking now?
Nope. It is for God, not imperfect men, to judge each of us as individuals.
Or am I finally at a stage where I can "surface" and see with some clarity?
Bingo. You hit the nail on the head.
Sometimes I fear the ping pong game in my head is driving me to insanity. The guilt is so overwhelming, yet when I really analyze it, I don't think I'm really that evil. I love God and want to be a good person. I thank him for my wife. Am I alone in these feelings?
No, again, your indoctrination in the cult of JWs is to blame for your confusion and lack of feeling ?sane?. In time, you will feel fine.
Cheers, and Welcome!!
