Awwwww..
I'm so sorry.. =(
*Hugs for you*!!
I can sort of understand where you're coming from. Being a believer is, indeed, easier in many ways. Theists get this cool imaginary friend that is always there for them. They get the promise of an eternal afterlife. They get simple rules to follow, and a book to turn to for all the answers!
But still.. On the other side.. Who wants easy, right..?
Shouldn't knowing the truth be the most important thing of all? I sure think it should! Why would you wish to delude yourself? Why would you wish to get stuck in a sugar-coated fairytale? It might be sweet for a while, perhaps. But not authentic in any way! And eventually you would choke on all the fake premises and want out. I'm completely sure of it...
Besides, see the positive things:
You have a sense of freedom that they will never have! You have rationality. Reality. The ability to think for yourself without being told what to do by an ancient fable full of nonsense! You have the opportunity to seize this one life and enjoy it for everything it is.. The fact that it is the only one you will ever get just makes it even the more precious, don't you think..? It sure is like that for me! =)
Don't try converting to anything. It would be useless.. Seems like you are one of those people who actually see reality for what it is. And that is quite a bit like having swallowed the red pill and gotten yourself unplugged from the matrix, so to speak.. You can no longer reverse it and go back to take the blue one. You cannot unlearn the truth once you have realized it! Sorry, but that's just the way it goes..
Instead of looking for what you need in life in fake gods, religion and such, try looking for it in your fellow human beings instead! Yourself, friends and family.. Those are real, tangible beings who can be there for you in difficult situations. Individuals who actually do exist. People who care..
If you miss some sort of spirituality, you can get a very similar feeling from listening to music, being in nature, writing, or just being in love with someone.. I love those feelings more than anything! You don't need anything supernatural when you can find it all in other places! Just try it out. Try finding something that gives YOU meaning.. I wish you all the best, girlie! =)
