I think you are having some kind of crisis. Probably because you were a witness with you mom, and then walked away and jumped in the frying pan with drugs, sex, etc.
That happens a lot to jws who were told Armageddon is coming soon and a paradise earth is just around the corner.
I was raised a witness too, but never really accepted it. Like you I also need evidence that Armageddon by God is coming soon but there really is no evidence, just a book with ancient stories that most of the Western world would argue it’s God inspired word, yet most don’t really read it or follow it.
I think the fact that you have a daughter is a good thing. You have someone that depends on you. So you need to make sure she understands the world she was brought in.
That means you need to start researching subjects like history, religion, human nature, evolution, and subjects that will help you understand why the world is like it is. You also need to understand why God is not coming to save us. Also stay away from drugs, meaningless sex, self harm, and get help if you are thinking of suicide.
Be patient and try not to despair so much. The Watchtower religion is not really a good environment to grow in. It’s a religious Doomsday cult that cultivates fear on it members. That’s why you mum and brother are trying hard to get you back into the religion. They really believe Armageddon by God is coming soon. And they believe God is going to kill Billions of people.
As far as violence in the world and volcanoes, and earthquakes, those things have been happening long before the bible was even written. There hasn’t been a century in history where some catastrophic event hasn’t happened. And who knows what catastrophic event might happen in our time. But that’s no reason you should stop from enjoying the things life offers. Life can be amazing.
And you are right, the universe is a huge place. With thousands of galaxies bigger than our Milky Way Galaxy and with more Solar Systems bigger than our Solar System. Who knows if different lifeforms exist out there smarter than us.
Life is really amazing. You need to make the time to continue seeing and learning about it.
