It's not that hard to survive in this god forsaken freezer. Just offer lonely men your orifices for them to un-pressurize their piss-utensils. Offer them sex for food, drinks, money, lodging, et seq.
It gets harder when you are older. No one gives a shit about your existence. So you have to do dumpster diving, living in the underground supermarkets, moving around. It was fun when i was younger. Now it is very hard. I am typing this while inside a bathroom. I won't reveal the location because it's illegal and i might get thrown out. I suck their dicks regularly for them to let me be here, and sometimes they give me something to eat. I also use toilet papers to collect the blood and pus around my asshole and enjoy it as raw delicacy.
