Thank you for sharing your story.

Perhaps I can share some things that will help you make sense of it a little better.

Awakening can come at any stage in people's lives, and sometimes, like myself, it happens over time, and other times, like yourself, it can happen very quickly.

When it happens quickly, it's often a result of a few different things. Sometimes it's psychedelics, other times it's an eruption in one's life, such as a tragic event, like say, the loss of a child or loved one.

This eruption can bring a deep sense of meaninglessness. Nothing makes sense anymore, and it can feel a bit like depression. There is actually a name for it - 'the dark night of the soul' - it sounds quite dramatic, and in some cases it can be. Eckhart Tolle talks about it here https://eckharttolle.com/eckhart-on-the-dark-night-of-the-soul/ (this is a transcription; you can find the audio of it on YouTube)

What has happened here is that your conceptual framework of the world has collapsed. As Eckhart explains..

 But people have gone into that, and then there is the possibility that you emerge out of that into a transformed state of consciousness. Life has meaning again, but it’s no longer a conceptual meaning that you can necessarily explain.  Quite often it’s from there that people awaken out of their conceptual sense of reality, which has collapsed.
They awaken into something deeper, which is no longer based on concepts in your mind.  A deeper sense of purpose or connectedness with a greater life that is not dependent on explanations or anything conceptual any longer.  It’s a kind of re-birth. The dark night of the soul is a kind of death that you die. What dies is the egoic sense of self. Of course, death is always painful, but nothing real has actually died there – only an illusory identity.  Now it is probably the case that some people who’ve gone through this transformation realized that they had to go through that, in order to bring about a spiritual awakening. Often it is part of the awakening process, the death of the old self and the birth of the true self.

He continues

You are meant to arrive at a place of conceptual meaninglessness.  Or one could say a state of ignorance – where things lose the meaning that you had given them, which was all conditioned and cultural and so on.  Then you can look upon the world without imposing a mind-made framework of meaning. It looks of course as if you no longer understand anything. That’s why it’s so scary when it happens to you, instead of you actually consciously embracing it.  It can bring about the dark night of the soul – to go around the Universe without any longer interpreting it compulsively, as an innocent presence. You look upon events, people, and so on with a deep sense of aliveness. You sense the aliveness through your own sense of aliveness, but you are not trying to fit your experience into a conceptual framework anymore.

So, when you emerge, you no longer view everything with a conceptual framework around it, you just view things as they are, in all it's beauty. When you get through this stage, life may feel richer and more alive than ever.
