Go Back if you feel it will make you happy.
BUT I garuntee you will never be happy there because it's all built on lies and rubbish.
if you like hearing lies and believing them to be true, go back.
if the future you want sacrifices the present, go back (it's not the real future but so what?).
If you want conditional friends, go back.
If you want to be dominated by humans, go back.
if you want to cast off your own personality and be someone else, go back.
if you want others to judge your life and emotionally blackmail you, go back.
if serving an organization makes you happy, go back.
However if you want a LIFE that you live for you, then go out there and get one, because if you go back then YOU have given your life to them to control and decide for you what is right and wrong.
Please don't go back, the price is way too high.
