I suffer for about few months of existential thoughts. It's about "life,universe,why humans are here,what is all this and for what, what is life,is the life real? What is afterlife,what is eternity and what is time? etc"... All the intrusive thoughts,and they are like nightmare, I don't have answers and I get anxiety and big fears because of this. It's really,really scary.
I'm sitting for example in room with my familly, and then I start to think "How all this life and existence is so strange" and I imagine in my head planet earth and how we are small to huge universe,and then I freak out. Because of that kind of thinking now I look at the world from different perspective,it's like I'm not the old person anymore, everything now is little strange,life and all in this world. Is that sign that Ia'm crazy?
They said Nietzsche went crazy because of thinking about it too much, and THERE IS A PROBLEM.
I bet he was a human more stable and smart than me of course, but anyway he went crazy.
And I'm just a woman of 27 year who is even afraid of little bugs, so now you can even imagine how these intrusive thoughts about humans,universe,life etc.. make me scared, which mean if Nietzsche went crazy, then there is big chanse I will go crazy too :-(
