I spent most of my life thinking that I was crazy until I started doing psychedelics and learned the truth about reality.
The simple fact is that we are all just lost souls. We're all just bumbling shells, walking around, bumping into things, trying to interpret our senses, communicate with each other and figure out some semblance of purpose. And when you can realize that, then it's not hard to break down the various systems of belief that are in place and realize that they are all meaningless conjecture. In truth, we really have no clue about anything. All of our perceptions and beliefs are skewed by the filtering process that occurs between unconscious and conscious states. Not to mention that our species is completely isolated in our own thinking.
Let's put it this way. As fundamental units, we are completely ignorant, yet at the same time we have the power to literally create our own reality. Maybe this was the intended point. Regardless... When you look at each individual as a wholly self-sufficient vessel who has the power to create their own reality, then you see that there is no such thing as "crazy."
We're all just trying to survive and create the world that we want to live in. Parents, schools, churches, organizations, governments, psychologists, scientists, etc... they all have one common agenda and that is to get as many people as possible to subscribe to their "reality." If you have a different perspective then they label you as diseased.
Sadly, this system isn't in place to give people freedom and to allow them to follow their dreams and reach their full potential. It's nothing more than an effort to exert power, create ignorance and give you just enough to keep you from revolting.
Psychedelics we're phased out of religions for this exact reason. And they're outlawed by governments for this exact reason.
Personally, I don't really believe in all these "mental disorders." I think that the vast majority of disorders are nothing more than warning signs that our unconscious is trying to convey to our conscious minds. You've got ADD? No you don't... Your unconscious is just trying to tell you that you're on the wrong path. Are you depressed? Well, no crap, this world is a horrible place and every day we are having more and more freedoms taken away and becoming slaves of a society, rather than owners of our reality. But you know... Instead of actually listening to these warning signs and exploring our own minds and desires, most people just want to take a bunch of pills and forget about it all.
It's the same thing with our bodies and diets. We're filling our bodies with nothing but toxins and synthetic crap.
Life has become so unnatural in every aspect and as far as I am concerned, humanity has wandered off on some obsessive thought and abandoned all hope.
Realize that the world is backwards, people are ignorant, everything is unnatural and that we are all slaves... I spent my whole life trying to fit into the system, but it wasn't until I realized all of these things to be true that I was able to rise above it and begin to truly live for the first time. You just have to cut against the grain and create your own reality regardless of what the system tells you. That's the only way anyone will ever truly be happy.
