Theburstbubble, welcome to reality...
How have people adapted to life outside the truth?
Everyone adapts in different ways. I had a lifetime of beliefs to unlearn and replace with beliefs and ideas based on critical thinking and evidence. It's scary and exhilarating. And, you may want to seek counseling (e.g. there are therapists who specialize in cults). Oh, and you will know you are making progress when you stop calling it "the Truth".
Making friends?Have you found your new friends to be as genuine?
Lots. And the cool thing is that these friends don't leave you if they disagree with you.
How about faith? I feel like I still want to believe in God but don't know even where to begin.
One place to begin is to ask yourself "why do you feel you still want to believe in God?". This is a question that most of us were never afforded the opportunity to ask. We were simply taught to accept this at face value with the same evidence we thought the JWs were "the Truth". How did that work out for you? So, maybe a good place to start is to ask a lot of questions especially ones that start with "Why?"... Take your time, challenge all your assumptions, and be gentle on yourself.
For what is worth, I am an atheist now and see no reason for faith. Faith ultimately comes to believing in something without good demonstrable evidence or evidence to the contrary. That did not seem like a path to truth to me. And, after some time I also realized that religion does not have a monopoly on those "spiritual" experiences, the sense of awe, wonder, joy, etc. You can have those feelings and experiences in other ways,
