Me too, I relate to that possum, nice to meet you, I also had my eyes opened by a fabulous philosophy uni course. Forever grateful to thr Open University..saved my life. I am sorry for your suffering and that of your family, especially your mum, my father too is an alcoholic. Your Dad I feel probably uses the wtbts as an emotional crutch..considering the hell he must have been through.
PS for an inspirational humanist film watch Chris Nolans Interstellar, just saw it highly recommended!
