Wow that makes so much sense and this is a concept i came across so much times in books.
There is a great book written by Chris Bache, called LSD and Mind of the Universe. In this book Chris tells his learnings after taking 73 heroic doses of LSD during 20 years.
He passes through some very hard stuff to deal with, like being Millions of women living mundane lives, being the protector of his daughter from rapists and figuring out that he also is the rapist, living this cosmic joke you've experienced a dozen times...
He explains that these unbearable experiences have only one purpose, making us better as individuals but also as the whole human race, he believes that all his work (and yours, and mine) have only one purpose: make our species evolve, find its way through all the political, economical and ecological crisis.
This lonely god you're describing, He is us, and He needs to shake us hardly in order for us to recognise Him and contemplate what he has been doing for billion years.
This is brave, my second experience with ayahuasca was so frightening, 5 hours of pure hell non-sense, being cut in pieces and scattered all around while some freaky entities were performing some surgical stuffs on the pieces of my body. It took me 5 years to integrate that experience and to understand that instead of doing 20 years of therapy without feeling any significant changes in my life, it all happened in 5 hours, and I was renewed.
Take some time, treat your body well, read some good books and time will make its work
