Goodbye... Also, if you come back again, you have no one but yourself to blame because your 'past' is the present time too, Some people hate it when people constantly say their going to leave then come back and keep doing the same thing, and you have been doing this but always say 'its your past' and say you tried to show us you changed, but you can not change if you are still doing the same thing of your past.
Good luck in whatever else you do.
