Im sorry to hear you are having such family difficulties, is there anyone you can confide in, i dont know the story behind you leaving or even how old you are, but im concerned to hear that you feel there is no other way out but to leave.
Maybe you can call in to an internet cafe and post on pet-talk rather than leave the website altogether.
Well take care wont you, and feel free to pm me if you wish, i am more than happy to listen ok.
