You were strangers with people before you become friends with them. and it is the worst thing in life if you again become strangers with them. It really hurts. but the most tragic part is that it is only you who gets hurt over it. The other ones don’t feel anything for losing you.
They just want to hurt you and you are hurting more for seeing them having no feelings for you. Now the ones you once loved are turned into a zombie, who just want to hurt you with no feelings of regret for doing so. and then every body you once loved turned into the same zombie and you end up being the only Human being in the city of Zombies. and then you release that the problem is not the zombies any more but you yourself for not becoming a Zombie and still being a Human. and then you are just screaming for help and wishing from those zombies to come and hurt you and turn you into one of them.
