@Libby - I think it's really cool that you went back through my posts on here and my journey out. Yes, my wife's first birthday party was so much fun. It's about that time again, though this year will be more subdued. We can't do a big blowout every year.
As you get farther away from the cult the fear of Armageddon will fade. At first I felt a lot of "but what if they're right", but hanging around a place like this reinforces how wrong they are and keeps you from backsliding into the brainwashing.
As far as purpose in life, life has the meaning that you give it. Think about it. JWs gave it a certain meaning and you and I bought that. If we were in India the Hindus might give it a totally different meaning and we likely would have bought that. So instead of getting your purpose from your culture or religion or other influences, you now have the ability to decide for yourself what that purpose is to be. I look around me at the plants and animals and they all have a purpose on this earth even if it isn't some eternal purpose. Sometimes they're food for another creature, sometimes they help some other creature grow, etc.
What is my purpose? I don't think it's clearly defined, but I can't go wrong with try to do no harm, help others, and be the best version of myself that I can be. If I've done that, at the end of my life when I look back, I'll be satisfied. Will I struggle with the thought of death? Maybe. I do struggle with that quite a bit. Okay, a lot. But I also know that's just because JWs put the idea of permanence in my head. Buddhists believe in impermanence and teach that as a concept. Had I been raised with that, I'd have no problem. Let's face it, everything around us points to a cycle of life and death. Whether it's the seasonal patterns from Spring to Winter or life on the plains of Africa for the animals that wander, death is as much a part of life as anything. Life goes on though. Life is quite the indomitable force. Will my life or your life go on after death in some other realm? Nobody knows. If there is some sort of loving creator that gives us an afterlife, then my life plan of doing no harm and trying to be the best version of myself and helping others surely will be enough. If there isn't, then I'll have lived a good life and mattered to the people I've come in contact with, and that's more than a lot of people get out of life.
