If this can help, my first step of salvation was to put any belief I had aside for a moment, just to focus on myself. I am not talking about narcissism, I am talking about introspection. Tell yourself now that you're freed from that organization, you can do whatever you want. Feel free to think by yourself, not waiting for someone else like you were taught to in the JW to think in your place. You are from now on free to experiment everything you wanted so much but couldn't because of the fear of beeing disfellowshipped. Do not even fear of beeing destroyed in a hypotetic Harmagedon, cause in no way you have to believe it, may it be true or not. It is a good thing for now, as you said, to care less for others and more for yourself. It may appear egocentric, but it is necessary to restrength your power to decide your own way of life. Geting information on sites written from ex-JW may afford great help, and feel free to make research on every aspect of the doctrine you were taugh. You may be surprised of what good information on major issues can provide help to regain some good critical thinking, all for a better understanding of the real world we all live in, a place surprisingly better than you actually think it is.
Not all things can be seen all white or all black (the Us and Them syndrome, in the WT). There is color everywhere, go out and see for yourself. Don't wait forever a paradise that is going farther everytime you think it's within reach. Thinking you are in somewhat a paradise here at this present time, what I think the actual world is (and I am not a dreamer, i just stopped thinking about the world as a bad place to live, only narrow minded persons make you think it actually is when it's not)it is worth a paradise many times promised but failed to come on time. So go outside, make new friends (although I know it is not easy), feel free to experiment, live your life as you always wanted to live it. It may sounds difficult at this time to do, but it is worth the effort. It will be good to feel free again, believe me.
