Zero and others here who have left the baby and the bath water,
God is not just a myth, now you may reason Him so due to the abuse you've experienced at the hands of the WTS, and for that, it is sad. However, I wish to assure you that God does not hold your reactions against you, but He does exists, and you know that He does, but for now, you need a 'break' from the 'authority' and 'control' in your life, and for that I cannot blame you.
Whatever you do, do the best you can and do good to others, and make the best of your life AFTER the WTS. I know it can be painful, but always be assured of God's love for you, that He is not the monster that was painted out to you, nor does he force you to read magazines upon magazines to discover Who He is, and that in the coming days you will eventually meet with Him and He will teach you of His real ways, and that we shall all walk in His ways and be joyful and content therein, not as members of a religious sect, but as free agents under a loving God and Father of us all.
Don't give up hope, life is truly like a shining light that does indeed get brigther and brighter, just live it to the full and don't regret what you have lived, learn from it, and move on.
