The truth about life and why we're here is what I mean by truth
It was difficult at first for me, because the Watchtower belief system is so absolute, they, and only they have "The Truth", the answers are spelled out for you: just obey. It was painful to realize that they lied, because then what were the answers? It was scary and uncomfortable. I grieved the loss of a belief system.
Being as I couldn't go backward I had just had to move forward and hope the answers came. It was difficult at first, but as time went on it got easier. I eventually realized that no one had all the answers and that's OK. If God exists and is good them I am sure he can read my heart and know I tried my best. I don't think anyone religion has all the answers, I have found a few that were much more welcoming and kind and that allow for individuality and freedom of thought and no doctrine, but ultimately I decided I am happy as I am, just being the best I can be.
You may come to a completely different conclusion, but that is your spiritual journey to follow. Just take in one day at a time, it's a process.
