I've become very selfish and rude and very apathetic towards everything and everyone.I always thought the values that jw's taught were really good
Maybe you have always been selfish, rude and apathetic towards other people. The difference is that while you were under the influence of JW dogma, you were scared into submission and you behaved like a good person, but the core of your person has always been the same.
It's time to get a moral compass, without having to resort to the guidance of a book that contains a morality that was appropriate 2,500 years ago. Join charitable groups, real charitable groups. Participate in community efforts to improve your community. In other words, befriend and learn from the real good people, not pious hypocrites driven by self interest to get a reward or approval.
