The problem with trying to discover who we are, is that as we discard the agendas of groups, we find little that we have actually thought through.
My only advice is, take your time. Whatever "answers" are out there won't come in a month, and if they are packaged that way, you should reject them quickly.
Education education education. If you aren't afraid to enter another persons frame of reference, you can learn something even from theists. Atheists as well. There is no need to judge, only to listen.
Take your time.
I am fond of saying that over time, the fortunate ones discover who they already are. I am not saying that my beliefs haven't changed drastically since I left JW's. Far from it. But at the core of me, I discover parts of me that were untouched by the GB indoctrination efforts.
My biggest value of all is honesty, esp intellectual honesty. I made a promise to myself not to lie to the person in the mirror ever again, or to lie to another person just to spare their feelings. If I might be so bold, I suggest that as a possible core anchor for anyone who is rebuilding their life and "belief" system after exiting JW's.
How can you tell if you are being honest with yourself or not? If you refuse to listen to someone you disagree with, and reject it without question, and without considering it, then you aren't there yet. (among other criteria....)
Lastly, may I suggest a strong dose of pragmatism? This quality helps me to not be too idealistic, and to read the world I inhabit a little more accurately then I used to as a JW.
Good luck!
