How to cope with only being me? Nothing is real. You are not you. The "you" you are seeking is inaccessible.
We are all of part of the greater chaos which we are destined to be part of.
Think of this like, we are part of the screen which makes an image. We are just a pixel on that screen. We have no idea about what we are and what we can complete by existing.
We can only see other pixels around us. Like green or red color.
Only the "one" who created "us" will know the true meaning for our existence.
