Help I don't believe in anything anymore?

Everything is subjective...if you gave the pope a hit of DMT, he would be trippin balls and not care at all about God or the sacrament or any of that shite for about 10 minutes. see what i mean? if a goddamn chemical can change who you are, what does that say about who you are? it says that you don't mean anything, you're just a physical, chemical being and all your beliefs are just physical chemical things that can change very easily.
