Dude, seriously, just stop. People have handed you the answers. There's maybe half a dozen perfectly workable ones. Sometimes the game serves you a ♥♥♥♥ sandwich, and you have to deal with it. If you think tossing your cookies is harsh, wait until you see what happens when the zeds find or make an unanticipated weak spot in your defenses. You're going to die, horribly, unpleasantly, not-necessarily-quickly, and unavoidably, until you're ready for absolutely everything this game can throw at you. That's the game. Quitcherbitching. Play the game or don't. Your math is bad, your response to challenges is lazy and ignorant, your whining is infantile and seemingly endless and you don't just ignore, you flat-out reject every attempt to help you.
