i feel you, man. im the same way. a few months ago i had my own enlightenment of sorts, i felt like i understood the universe and that all perspectives on reality were just different ways of viewing the same thing, different paths in life. everything for a few months after were fucking peace, everything was cool, i felt like i was achieving my full potential in life, like i had some sort of a purpose, but then the feeling faded. i dont know why. i think life is what you make it, whatever you choose to pursue, if thats partying and taking it all as a joke, thats all that your life will consist of. if you follow a spiritual, deeper understanding of life, maybe youll eventually reach the peace your looking for. i dunno man, whatever answer youre looking for, i hope you find it.
